| 1 | Porous carbon coupled with an interlaced MoP–MoS2 heterojunction hybrid for efficient hydrogen evolution reaction显示文摘The design and development of electrocatalysts composed of non-noble-metal catalysts with both large surface area and high electrical conductivities are crucial for the hydrogen evolution reaction(HER).Here,a xylose-based porous carbon is coupled with a MoS2-Mo P heterojunction(MoS2-Mo P/FPC)hybrid and used as a promising catalyst for HER.The hybrid is prepared by immobilizing petal-like MoS2 nanosheets on porous carbon(MoS2/FPC),followed by controlling the phosphidation in Ar/H2 to form MoS2-Mo P/FPC.Red phosphorus provides the P species that can induce the construction of the heterojunction under the reducing atmosphere,along with the generation of a Mo P phase and the splitting of the MoS2 phase.The as-prepared MoS2-Mo P/FPC catalyst offers a low overpotential of 144 mV at a current density of 10 m A cm^-2 and a small Tafel slope of 41 m V dec^-1 for the HER in acidic media,as well as remarkable stability.Apart from the active nature of the hybrid,its outstanding activity is attributed to the MoS2-Mo P heterojunction,and the good charge/mass-transfer ability of porous carbon.This strategy provides a new method to develop and design low-cost and high-performance catalysts for the HER. | Qiusheng Zhou Jianrui Feng Xinwen Peng Linxin Zhong Runcang Sun | 2020 | Journal of Energy Chemistry2020，29，6： | 2 |

| 4 | Biomass-based N doped carbon as metal-free catalyst for selective oxidation of D-xylose into D-xylonic acid显示文摘Rational design and facile preparation of low-cost and efficient catalysts for the selective converting of biomass-derived monosaccharides into high value-added chemicals is highly demanded,yet challenging.Herein,we first demonstrate a N doped defect-rich carbon(NC-800-5)as metal-free catalyst for the selective oxidation of D-xylose into D-xylonic acid in alkaline aqueous solution at 100℃ for 30 min,with 57.4%yield.The doped graphitic N is found to be the active site and hydroxyl ion participating in the oxidation of D-xylose.Hydroxyl ion and D-xylose first adsorb on NC-800-5 surface,and the aldehyde group of D-xylose is catalyzed to form germinal diols ion.Then,C–H bond break to yield carboxylic group.Furthermore,NC-800-5 catalyst shows high stability in recycled test. | Zengyong Li Yiming Huang Xiao Chi Di Li Linxin Zhong Xuehui Li Chuanfu Liu Xinwen Peng | 2022 | Green Energy & Environment2022，7，6： | 1 |

| 6 | Quaternized chitosan-assisted in situ synthesized CuS/cellulose nanofibers conductive paper for flexible electrode显示文摘Cellulose nanofibers(CNF)are considered to be a potential substrate of energy material for energy storage devices due to the foldable,lightweight,recyclable and environmentally friendly feature.However,the energy materials tend to distribute unevenly or fall off from CNF easily,resulting in the decrease of the devices’overall performance.Here,for the first time,we used quaternized chitosan(QCS)as stabilizer and adhesive to in situ synthesize and deposite copper sulfide nanocrystals(CuS-NCs)on CNF and further obtained the conductive paper for flexible supercapacitors.In the presence of QCS,CuS-NCs deposited in situ on CNF can be capped and stabilized by the QCS molecular chains for uniform distribution,which is conducive to the capacitive behavior and electrochemical stability of composite paper.The result shows that the specific capacitance of the composite paper was as high as 314.3 F/g at a current density of 1 A/g,a high rate capacitance of 252.6 F/g was achieved even at a high current density of 10 A/g.It reveals that the composite paper exhibited better electrochemical performance than many other CuS-based electrode materials for supercapacitor.More importantly,the composite paper performed well in various folding state without changing much electrochemical performance.Therefore,this work provides a novel strategy to in situ fabricate paper-based electrode for nextgeneration flexible energy-storage system. | Xiujie Huang Bichong Luo Chuanfu Liu Linxin Zhong Dongdong Ye Xiaoying Wang | 2021 | Nano Research2021，14，7： | 0 |
| 7 | Base-free selective oxidation of monosaccharide into sugar acid by surface-functionalized carbon nanotube composites显示文摘Selective oxidation of biomass-derived monosaccharide into high value-added chemicals is highly desirable from sustainability perspectives.Herein,we demonstrate a surface-functionalized carbon nanotubesupported gold(Au/CNT-O and Au/CNT-N)catalyst for base-free oxidation of monosaccharide into sugar acid.Au/CNT-O and Au/CNT-N surfaces successfully introduced oxygen-and nitrogen-containing functional groups,respectively.The highest yields of gluconic acid and xylonic acid were 93.3%and 94.3%,respectively,using Au/CNT-N at 90℃ for 240 min,which is higher than that of using Au/CNT-O.The rate constants for monosaccharide decomposition and sugar acid formation in Au/CNT-N system were higher,while the corresponding activation energy was lower than in Au/CNT-O system.DFT calculation revealed that the mechanism of glucose oxidation to gluconic acid involves the adsorption and activation of O_(2),adsorption of glucose,dissociation of the formyl C-H bond and formation of O-H bond,and formation and desorption of gluconic acid.The activation energy barrier for the glucose oxidation over Au/CNT-N is lower than that of Au/CNT-O.The nitrogen-containing functional groups are more beneficial for accelerating monosaccharide oxidation and enhancing sugar acid selectivity than oxygen-containing functional groups.This work presents a useful guidance for designing and developing highly active catalysts for producing high-value-added chemicals from biomass. | Zengyong Li Di Li Linxin Zhong Xuehui Li Chuanfu Liu Xinwen Peng | 2023 | Chinese Chemical Letters2023，34，11： | 0 |
| 8 | Defect reduction to enhance the mechanical strength of nanocellulose carbon aerogel显示文摘Carbon aerogels prepared from renewable nano building blocks are rising-star materials and hold great promise in many fields.However,various defects formed during carbonization at high temperature disfavor the stress transfer and thus the fabrication of flexible carbon aerogel from renewable nano building blocks.Herein,a structural defect-reducing strategy is proposed by altering the pyrolysis route of cellulose nanofiber.Inorganic salt that inhibits the generation of tar volatilization during pyrolysis can prevent the formation of various structural defects.Microstructure with fewer defects can reduce stress concentration and remarkably enhance the compressibility of carbon aerogel,thus increasing the maximum stress retention of carbon aerogel.The carbon aerogel also has high stress sensor sensitivity and excellent temperature coefficient of resistance.The structural defect-reducing strategy will pave a new way to fabricate high-strength carbon materials for various fields. | Haihong Lai Zehong Chen Hao Zhuo Yijie Hu Xuan Zhao Jiwang Yi Hongzhi Zheng Ge Shi Yifan Tong Ling Meng Xinwen Peng Linxin Zhong | 2024 | Chinese Chemical Letters2024，35，1： | 0 |
| 9 | Metal coordination assists fabrication of multifunctional aerogel显示文摘Interfacial design is one of the most promising ways in improving mechanical properties of nanocomposites.In this work,a multifunctional aerogel with excellent mechanical performances,sensing sensitivity,and fire retardancy is fabricated by taking advantage of metal coordination between biopolymer and Fe3+.Montmorillonite(MMT)nanosheets are added to induce a‘brick and mortar’structure.The coordination remarkably reduces structural defects,leading to well-formed lamellas that can effectively distribute stress under sever compression without plastic deformation.The structural merits impart the aerogel highly reversible compressibility even at 99%strain and superior durability.Besides,it demonstrates high sensing performance in wearable health monitoring devices,and shows fire resistance property that can maintain elasticity in a flame.The work offers a facile and effective method to create multifunctional aerogels from various polymers. | Yijie Hu Hao Zhuo Zehong Chen Xinwen Peng Linxin Zhong Runcang Sun | 2021 | Journal of Materials Science & Technology2021，，12： | 0 |
| 10 | Thermoelectric generator based on anisotropic wood aerogel for low-grade heat energy harvesting显示文摘Thermoelectric generators(TEGs)have received increasing attention due to their potential to harvest low-grade heat energy(<100℃ )and provide power for the Internet of Things(IoT)and wearable electronic devices.Herein,a wood-based ordered framework is used to fabricate carbon nanotube/poly(3,4-ethylenedioxythiophene)(CNT/PEDOT)wood aerogel for TEG.The prepared CNT/PEDOT wood aerogel with an anisotropic structure exhibits a low thermal conductivity of 0.17 W m^(−1)K^(−1)and is advantageous to develop a sufficient temperature gradient.Meanwhile,CNT/PEDOT composites effectively decouple the relationship between the Seebeck coefficient and electrical conductivity by energy filtering effect to enhance thermoelectric(TE)output properties.The vertical TEG assembled by the CNT/PEDOT wood aerogels reveals an output power of 1.5μW and a mass-specific power of 15.48μW g^(−1)at a temperature difference of 39.4 K.Moreover,the layered structure renders high compressibility and fatigue resistance.The anisotropic structure,high mechanical performance,and rapid thermoelectric response,enabling the TEG based on CNT/PEDOT wood aerogel offer opportunities for continuous power supply to low-power electronic devices. | Xuan Zhao Zehong Chen Hao Zhuo Yijie Hu Ge Shi Bing Wang Haihong Lai Sherif Araby Wenjia Han Xinwen Peng Linxin Zhong | 2022 | Journal of Materials Science & Technology2022，，25： | 0 |
