| 1 | Preparation of nitrogen and sulfur co-doped ultrathin graphitic carbon via annealing bagasse lignin as potential electrocatalyst towards oxygen reduction reaction in alkaline and acid media显示文摘Renewable lignin used for synthesizing materials has been proven to be highly potential in specific electrochemistry.Here,we report a simple method to synthesize nitrogen and sulfur co-doped carbon nanosheets by using bagasse lignin,denoted as lignin-derived carbon(LC).By adjusting the ratio of nitrogen source and annealing temperature,we obtained the ultrathin graphitic lignin carbon(LC-4-1000)with abundant wrinkles with high surface area of 1208 m2g_1 and large pore volume of 1.40 cm3g_1.In alkaline medium,LC-4-1000 has more positive half-wave potential and nearly current density compared to commercial Pt/C for oxygen reduction reaction(ORR).More importantly,LC-4-1000 also exhibits comparable activity and superior stability for ORR in acid medium due to its high graphitic N ratio and a direct four electron pathway for ORR.This study develops a cost-effective and highly efficient method to prepare biocarbon catalyst for ORR in fuel cells. | Yixing Shen Feng Peng Yonghai Cao Jianliang Zuo Hongjuan Wang Hao Yu | 2019 | Journal of Energy Chemistry2019，28，7： | 5 |

| 3 | Syngas production by dry reforming of the mixture of glycerol and ethanol with CaCO3显示文摘The reduction of CO2 emission is crucial for the mitigation of climate change.A considerable amount of industrial CO2 can be absorbed in the form of carbonates through high-temperature sorption processes.In this regard,the efficient conversion of carbonates to value-added products will provide an economically viable method for the sustainable usage of carbon compounds.Herein,we report a promising solution involving the use of a glycerol and ethanol mixture as a hydrogen donor in the dry reforming process with CaCO3 to produce syngas.A series of metal active components,including Ni,Fe,Co,Cu,Pt,Pd,Ru,and Rh,was used to promote this reaction.Ni showed comparable performance with that of Pd,but outperformed Co,Fe,Cu,Rh,Ru,and Pt.Approximately 100%conversion of glycerol and ethanol,~92%selectivity of synthesis gas(H2 and CO),and a H2/CO ratio of^1.2 were achieved over CaCO3 containing10 wt%Ni(10Ni-CaCO3).Meanwhile,the CO2 concentration was less than 5 vol%,indicating that most of the CO2 captured by the carbonate can be transformed into chemicals;however,they cannot simply be emitted.The CO2 released from the decomposition of CaCO3 not only adjusted the ratio of H2 to CO but also eliminated cokes to guarantee the CO2 absorption-conversion cyclic stability in the absence of steam and at high temperatures. | Chengxiong Dang Shijie Wu Guangxing Yang Yonghai Cao Hongjuan Wang Feng Peng Hao Yu | 2020 | Journal of Energy Chemistry2020，29，4： | 1 |

| 5 | Noble-metal-based high-entropy-alloy nanoparticles for electrocatalysis显示文摘Since the two seminal papers were published independently in 2004, high-entropy-alloys(HEAs) have been applied to structural and functional materials due to the enhanced mechanical properties, thermal stability, and electrical conductivity. In recent years, HEA nanoparticles(HEA-NPs) were paid much attention to in the field of catalysis for the promoted catalytic activity. Furthermore, the various ratios among the metal components and tunable bulk and surface structures enable HEAs have big room to enhance the catalytic performance. Especially, noble-metal-based HEAs displayed significantly improved performance in electrocatalysis, where the ‘core effects’ were employed to explain the superior catalytic activity. However, it is insufficient to understand the essential mechanism or further guide the design of electrocatalysts. Structure–property relationship should be disclosed for the catalysis on HEA-NPs to accelerate the process of seeking high effective and efficient electrocatalysts. Therefore, we summarized the recent advances of noble-metal-based HEA-NPs applied to electrocatalysis, such as hydrogen evolution reaction, oxygen evolution reaction, oxygen reduction reaction, methanol oxidation reaction, ethanol oxidation reaction, formic acid oxidation reaction, hydrogen oxidation reaction, carbon dioxide reduction reaction and nitrogen reduction reaction. For each electrocatalytic reaction, the reaction mechanism and catalyst structure were presented, and then the structure–property relationship was elaborated. The review begins with the development, concept, four ‘core effect’ and synthesis methods of HEAs. Next,the electrocatalytic reactions on noble-metal-based HEA-NPs are summarized and discussed independently. Lastly, the main views and difficulties pertaining to structure–property relationship for HEAs are discussed. | Xianfeng Huang Guangxing Yang Shuang Li Hongjuan Wang Yonghai Cao Feng Peng Hao Yu | 2022 | Journal of Energy Chemistry2022，31，5： | 1 |
| 6 | Bi-functional particles for integrated thermo-chemical processes:Catalysis and beyond显示文摘Particulate materials possessing dual functionalities have received tremendous investigations in many fields,owing to their superiority over mono-functional counterparts and their potential for process integration and intensification.This review focuses on bi-functional catalytic particles which also serve as sorbents/adsorbents or heat suppliers in the scheme of various thermo-chemical processes,enabling inherent separation or energy conservation within single-step operation.Bi-functional particles applied for integration of reaction and separation including sorption-enhanced hydrogen production and integrated capture and catalytic conversion processes are reviewed in detail,providing insights into material design and key performance indicators.On the other hand,bi-functional particles applied for integration of reaction and non-thermal radiation heating,including electrothermal and photothermal assisted heterogeneously catalyzed reactions,are also reviewed,with emphasis on the material property and energy efficiency improvement.These bi-functional particles show broad adaptability and feasibility in various reactions operated in integrated and intensified schemes,affording huge potentials for further improving productivity and efficiency in thermo-chemical processes. | Hanke Li Chengxiong Dang Guangxing Yang Yonghai Cao Hongjuan Wang Feng Peng Hao Yu | 2021 | Particuology2021，19，3： | 1 |

| 12 | Exogenous-organic-matter-driven mobilization of groundwater arsenic显示文摘The potential release capacity of arsenic(As)from sediment was evaluated under a high level of exogenous organic matter(EOM)with both bioreactive and chemically reactive organic matters(OMs).The OMs were characterized by FI,HIX,BIX,and SUVA254 fluorescence indices showing the biological activities were kept at a high level during the experimental period.At the genus level,Fe/Mn/As-reducing bacteria(Geobacter,Pseudomonas,Bacillus,and Clostridium)and bacteria(Paenibacillus,Acidovorax,Delftia,and Sphingomonas)that can participate in metabolic transformation using EOM were identified.The reducing condition occurs which promoted As,Fe,and Mn releases at very high concentrations of OM.However,As release increased during the first 15-20 days,followed by a decline contributed by secondary iron precipitation.The degree of As release may be limited by the reactivity of Fe(hydro)oxides.The EOM infiltration enhances As and Mn releases in aqueous conditions causing the risk of groundwater pollution,which could occur in specific sites such as landfills,petrochemical sites,and managed aquifer recharge projects. | Fan Feng Yonghai Jiang Yongfeng Jia Xinying Lian Changjian Shang Meng Zhao | 2023 | Environmental Science and Ecotechnology2023，，3： | 0 |
| 13 | Efficient nanozyme engineering for antibacterial therapy显示文摘Antimicrobial resistance(AMR)poses a huge threat to human health.It is urgent to explore efficient ways to suppress the spread of AMR.Antibacterial nanozymes have become one of the powerful weapons to combat AMR due to their enzyme-like catalytic activity with a broad-spectrum antibacterial performance.However,the inherent low catalytic activity of nanozymes limits their expansion into antibacterial applications.In this regard,a variety of advanced chemical design strategies have been developed to improve the antimicrobial activity of nanozymes.In this review,we have summarized the recent progress of advanced strategies to engineer efficient nanozymes for fighting against AMR,which can be mainly classified as catalytic activity improvement,external stimuli,bacterial affinity enhancement,and multifunctional platform construction according to the basic principles of engineering efficient nanocatalysts and the mechanism of nanozyme catalysis.Moreover,the deep insights into the effects of these enhancing strategies on the nanozyme structures and properties are highlighted.Finally,current challenges and future perspectives of antibacterial nanozymes are discussed for their future clinical potential. | Yonghai Feng Funing Chen Jessica M Rosenholm Lei Liu Hongbo Zhang | 2022 | Materials Futures2022，1，2： | 0 |
| 14 | Production of high-purity hydrogen from paper recycling black liquor via sorption enhanced steam reforming显示文摘Environmentally friendly and energy saving treatment of black liquor(BL),a massively produced waste in Kraft papermaking process,still remains a big challenge.Here,by adopting a NieCaOeCa_(12)Al_(14)O_(33) bifunctional catalyst derived from hydrotalcite-like materials,we demonstrate the feasibility of producing high-purity H_(2)(~96%)with 0.9 mol H_(2) mol^(-1) C yield via the sorption enhanced steam reforming(SESR)of BL.The SESRBL performance in terms of H_(2) production maintained stable for 5 cycles,but declined from the 6th cycle.XRD,Raman spectroscopy,elemental analysis and energy dispersive techniques were employed to rationalize the deactivation of the catalyst.It was revealed that gradual sintering and agglomeration of Ni and CaO and associated coking played important roles in catalyst deactivation and performance degradation of SESRBL,while deposition of Na and K from the BL might also be responsible for the declined performance.On the other hand,it was demonstrated that the SESRBL process could effectively reduce the emission of sulfur species by storing it as CaSO_(3).Our results highlight a promising alternative for BL treatment and H_(2) production,thereby being beneficial for pollution control and environment governance in the context of mitigation of climate change. | Hanke Li Shijie Wu Chengxiong Dang Guangxing Yang Yonghai Cao Hongjuan Wang Feng Peng Hao Yu | 2021 | Green Energy & Environment2021，6，5： | 0 |
| 15 | Ambipolar tribotronic transistor of MoTe_(2)显示文摘Two-dimensional(2D)tribotronic devices have been successfully involved in electromechanical modulation for channel conductance and applied in intelligent sensing system,touch screen,and logic gates.Ambipolar transistors and corresponding complementary inverters based on one type of semiconductors are highly promising due to the facile fabrication process and readily tunable polarity.Here,we demonstrate an ambipolar tribotronic transistor of molybdenum ditelluride(MoTe_(2)),which shows typical ambipolar transport properties modulated by triboelectric potential.It is comprised of a MoTe_(2)transistor and a lateral sliding triboelectric nanogenerator(TENG).The induced triboelectric potential by Maxwell’s displacement current(a driving force for TENG)can readily modulate the transport properties of both electrons and holes in MoTe_(2)channel and effectively drive the transistor.High performance tribotronic properties have been achieved,including low cutoff current below 1 pA·μm^(−1)and high current on/off ratio of~103 for holes and electrons dominated transports.The working mechanism on how to achieve tribotronic ambipolarity is discussed in detail.A complementary tribotronic inverter based on single flake of MoTe_(2)is also demonstrated with low power consumption and high stability.This work presents an active approach to efficiently modulate semiconductor devices and logic circuits based on 2D materials through external mechanical signal,which has great potential in human–machine interaction,intelligent sensor,and other wearable devices. | Yonghai Li Jinran Yu Yichen Wei Yifei Wang Liuqi Cheng Zhenyu Feng Ya Yang Zhong Lin Wang Qijun Sun | 2023 | Nano Research2023，16，9： | 0 |
| 16 | Alternative Copper-Based Single-Atom Nanozyme with Superior Multienzyme Activities and NIR-II Responsiveness to Fight against Deep Tissue Infections显示文摘Nanozymes are considered to represent a new era of antibacterial agents,while their antibacterial efficiency is limited by the increasing tissue depth of infection.To address this issue,here,we report a copper and silk fibroin(Cu-SF)complex strategy to synthesize alternative copper single-atom nanozymes(SAzymes)with atomically dispersed copper sites anchored on ultrathin 2D porous N-doped carbon nanosheets(CuN_(x)-CNS)and tunable N coordination numbers in the CuN_(x) sites(x=2 or 4).The CuN_(x)-CNS SAzymes inherently possess triple peroxidase(POD)-,catalase(CAT)-,and oxidase(OXD)-like activities,facilitating the conversion of H_(2)O_(2)and O_(2)into reactive oxygen species(ROS)through parallel POD-and OXD-like or cascaded CAT-and OXD-like reactions.Compared to CuN_(2)-CNS,tailoring the N coordination number from 2 to 4 endows the SAzyme(CuN_(4)-CNS)with higher multienzyme activities due to its superior electron structure and lower energy barrier.Meanwhile,CuN_(x)-CNS display strong absorption in the second near-infrared(NIR-II)biowindow with deeper tissue penetration,offering NIR-II-responsive enhanced ROS generation and photothermal treatment in deep tissues.The in vitro and in vivo results demonstrate that the optimal CuN_(4)-CNS can effectively inhibit multidrug-resistant bacteria and eliminate stubborn biofilms,thus exhibiting high therapeutic efficacy in both superficial skin wound and deep implant-related biofilm infections. | Jiaxiang Bai Yonghai Feng Wenming Li Zerui Cheng Jessica MRosenholm Huilin Yang Guoqing Pan Hongbo Zhang Dechun Geng | 2023 | Research2023，，3： | 0 |
| 17 | Selective and effective oxidation of 5-hydroxymethylfurfural by tuning the intermediates adsorption on Co-Cu-CN_(x)显示文摘Co-based catalysts are promising alternatives to precious metals for the selective and effective oxidation of 5-hydroxymethylfurfural(HMF)to the higher value-added 2,5-furandicarboxylic acid(FDCA).However,these catalysts still suffer from unsatisfactory activity and poor selectivity.A series of N-doped carbon-supported Co-based dual-metal nanoparticles(NPs)have been designed,among which the Co-Cu_(1.4)-CN_(x) exhibits enhanced HMF oxidative activity,achieving FDCA formation rates 4 times higher than that of pristine Co-CN_(x),with 100%FDCA selectivity.Density functional theory(DFT)calculations evidenced that the increased electron density on Co sites induced by Cu can mediate the positive electronegativity offset to downshift the dband center of Co-Cu_(1.4)-CN_(x),thus reducing the energy barriers for the conversion of HMF to FDCA.Such findings will support the development of superior non-precious metal catalysts for HMF oxidation. | Tianyun Jing Shaokang Yang Yonghai Feng Tingting Li Yunpeng Zuo Dewei Rao | 2023 | Nano Research2023，16，5： | 0 |
| 18 | Cu,N codoped carbon nanosheets encapsulating ultrasmall Cu nanoparticles for enhancing selective 1,2-propanediol oxidation显示文摘In the selective oxidation of biomass-based 1,2-propanediol(PDO)with oxygen as the terminal oxidant,it is challenging to improve the lactic acid(LA)selectivity for nonnoble metal nanoparticles(NPs)due to their limited oxygen reduction rate and easy C-C cleavage.Given the high economic feasibility of nonnoble metals,i.e.,Cu,in this work,copper and nitrogen codoped porous carbon nanosheets encapsulating ultrafine Cu nanoparticles(Cu@Cu-N-C)were developed to realize highly selective of PDO oxidation to LA.The carbon-encapsulated ultrasmall Cu0NPs in Cu@Cu-N-C have high PDO dehydrogenation activity while N-coordinated Cu(Cu-N)sites are responsible for the high oxygen reduction efficacy.Therefore,the performance of catalytic PDO conversion to LA is optimized by a proposed pathway of PDO→hydroxylacetone→lactaldehyde→LA.Specifically,the enhanced LA selectivity is 88.5%,and the PDO conversion is up to 75.1%in an O_(2)-pressurized reaction system(1.0 MPa O_(2)),superior to other Cu-based catalysts,while in a milder nonpressurized system(O_(2)flow rate of 100 mL min-1),a remarkable LA selectivity(94.2%)is obtained with 39.8%PDO conversion,2.2 times higher than that of supported Au nanoparticles(1%Au/C).Moreover,carbon encapsulation offers Cu@Cu-N-C with strong leaching resistance for better recycling. | Yonghai Feng Min Yu Minjia Meng Lei Liu Dewei Rao | 2024 | Journal of Energy Chemistry2024，91，4： | 0 |
| 19 | Polymorphism of Kdo-Based Glycolipids:The Elaborately Determined Stable and Dynamic Bicelles显示文摘Understanding how the diversity of glycolipids,including how their chemical structures and composition affect their biological functions,is a remarkable fundamental challenge.In this work,we employed a rare monosaccharide,3-deoxy-Dmanno-2-octulosonic acid(Kdo)to build a simple and biomimetic model to understand the diversity of glycolipids from the viewpoint of supramolecular chemistry.Kdo was chosen not only because its unusual 8-carbon acidic carbohydrate backbone is very different from common hexoses,but also because of its key structural role in lipopolysaccharides and prevalence in bacteria,plant life,and algae.It was found that although both of the two Kdo-lipids S-Kdo and Kdo-S derived from the same carbohydrate backbone and gave bicelles as their self-assembled morphology,experimental results revealed that the self-assembly showed pathway complexity.Bicelle is the thermodynamic product of S-Kdo,while for Kdo-S,the bicelle is only a kinetically trapped state,which finally transforms to a ribbon.Molecular simulation clearly revealed the different packing of Kdo-lipids in the bicelles with different contribution from hydrogen bonds and electrostatic interactions. | Yingle Feng Long Li Qiqige Du Lu Gou Lei Zhang Yonghai Chai Ran Zhang Tongfei Shi Guosong Chen | 2022 | CCS Chemistry2022，4，7： | 0 |
