| 1 | Large-scale synthesis of N-doped carbon capsules supporting atomically dispersed iron for efficient oxygen reduction reaction electrocatalysis显示文摘The large-scale synthesis of platinum-free electrocatalysts for the oxygen reduction reaction(ORR)remains a grand challenge.We report the large-scale production of stable and active ORR electrocatalysts based on iron,an earth-abundant element.A core–shell zeolitic imidazolate framework–tannic acid coordination polymer composite(ZIF-8@K-TA)was utilized as the catalyst precursor,which was transformed into iron atoms dispersed in hollow porous nitrogen-doped carbon capsules(H-Fe-N_(x)-C)through ion exchange and pyrolysis.H-Fe-N_(x)-C fea-tures site-isolated single-atom iron centers coordinated to nitrogen in graphitic layers,high levels of nitrogen doping,and high permeability to incoming gases.Benefiting from these characteristics,H-Fe-N_(x)-C demonstrated efficient electrocatalytic activity(E_(1/2)=0.92 V,vs.RHE)and stability towards the ORR in both alkaline and acidic media.In ORR performance,it surpassed the majority of recently reported Fe-N-C catalysts and the standard Pt/C catalyst.In addition,H-Fe-N_(x)-C showed outstanding tolerance to methanol. | Hui Yang Yanfang Liu Xiaolu Liu Xiangke Wang He Tian Geoffrey I.N.Waterhouse Paul E.Krugere Shane GTelfer Shengqian Ma | 2022 | eScience2022，2，2： | 4 |

| 3 | CrN-Encapsulated Hollow Cr-N-C Capsules Boosting Oxygen Reduction Catalysis in PEMFC显示文摘Understanding the origin of the catalytic activity for the development of efficient catalysts is critical yet challenging.Herein,we report a simple strategy for the synthesis of chromium nitride nanoparticles(CrNNPs)encapsulated into hollow chromium-nitrogen-carbon capsules(CrN@H-Cr-N_(x)-C).The CrN@H-Cr-N_(x)-C demonstrated excellent electrocatalytic activity for the oxygen reduction reaction(ORR)in acidic solutions.When applied as a cathode material in a proton-exchange membrane fuel cell(PEMFC),the CrN@H-Cr-N_(x)-C achieved outstanding initial performance,which is better than that of the PEMFC with H-Cr-N_(x)-C cathode material.The CrN@H-Cr-N_(x)-C cathode also showed good stability over 110 h of operation.These results demonstrated that the coexistence of atomically dispersed CrN_(x) sites and sufficient CrNNPs is essential for excellent PEMFC performances.Density functional theory(DFT)studies further corroborated that CrNNPs can boost the ORR activity of H-Cr-N_(x)-C.This finding opens a new avenue for the fabrication of low-cost,highly active,and durable ORR catalysts for PEMFC and other applications. | Hui Yang Xu Wang Tao Zheng Nelly Cantillo Cuello Gabriel Goenaga Thomas A.Zawodzinski He Tian Joshua T.Wright Robert W.Meulenberg Xiangke Wang Zhenhai Xia Shengqian Ma | 2021 | CCS Chemistry2021，3，5： | 2 |
| 4 | De novo synthesis of bifunctional conjugated microporous polymers for synergistic coordination mediated uranium entrapment显示文摘This work reports a de novo synthesis of novel bifunctional conjugated microporous polymers(CMPs)exhibiting a synergistic-effect involved coordination behavior to uranium.It is highlighted that the synthetic strategy enables the engineering of the coordination environment within amidoxime functionalized CMP frameworks by specifically introducing ortho-substituted amino functionalities,enhancing the affinity to uranyl ions via forming synergistic complexes.The CMPs exhibit high Brunauer-Emmett-Teller(BET)surface area,well-developed three-dimensional(3D)networks with hierarchical porosity,and favorable chemical and thermal stability because of the covalently cross-linked structure.Compared with the amino-free counterparts,the adsorption capacity of bifunctional CMPs was increased by almost 70%,from 105 to 174 mg/g,indicating evidently enhanced binding ability to uranium.Moreover,new insights into coordination mechanism were obtained by in-depth X-ray photoelectron spectroscopy(XPS)analysis and density functional theory(DFT)calculation,suggesting a dominant role of the oxime ligands forming a 1:1 metal ions/ligands(M/L)coordination model with uranyl ions while demonstrating the synergistic engagement of the amino functionalities via direct binding to uranium center and hydrogen-bonding involved secondary-sphere interaction.This work sheds light on the underlying principles of ortho-substituted functionalities directed synergistic effect to promote the coordination of amidoxime with uranyl ions.And the synthetic strategy established here would enable the task-specific development of more novel CMP-based functional materials for broadened applications. | Boxuan Yu Lei Zhang Gang Ye Qingzhi Liu Jiongli Li Xudong Wang Jing Chen Shengming Xu Shengqian Ma | 2021 | Nano Research2021，14，3： | 2 |

| 6 | Core-satellite metal-organic framework@upconversion nanoparticle superstructures via electrostatic self-assembly for efficient photodynamic theranostics显示文摘The nanoplatforms based on upconversion nanoparticles(UCNPs)have shown great promise in amplified photodynamic therapy(PDT)triggered by near-infrared(NIR)light.However,their practical in vivo applications are hindered by the overheating effect of 980 nm excitation and low utilization of upconversion luminescence(UCL)by photosensitizers.To solve these defects,core-satellite metal-organic framework@UCNP superstructures,composed of a single metal-organic framework(MOF)NP as the core and Nd3+-sensitized UCNPs as the satellites,are designed and synthesized via a facile electrostatic self-assembly strategy.The superstructures realize a high co-loading capacity of chlorin e6(Ce6)and rose bengal(RB)benefitted from the highly porous nature of MOF NPs,showing a strong spectral overlap between maximum absorption of photosensitizers and emission of UCNPs.The in vitro and in vivo experiments demonstrate that the dual-photosensitizer superstructures have trimodal(magnetic resonance(MR)/UCL/fluorescence(FL))imaging functions and excellent antitumor effectiveness of PDT at 808 nm NIR light excitation,avoiding the laser irradiation-induced overheating issue.This study provides new insights for the development of highly efficient PDT nanodrugs toward precision theranostics. | Zhike Li Xi Qiao Guihua He Xin Sun Danhua Feng Liefeng Hu Hua Xu Hai-Bing Xu Shengqian Ma Jian Tian | 2020 | Nano Research2020，13，12： | 2 |

| 10 | Fabrication of Fe-POMs as Visible-light-active Heterogeneous Photocatalyst显示文摘Visible-light-active Fe-POMs was fabricated via precipitating Fe^3+with Keggin type polyoxometalates(H:PWi0a.H4SiWi204o or HsPMorOao)under solvothermal condition.The as-prepared Fe-POMs were denoted as FePW.FeSiW and FePMo,respectively.Among the three kinds of Fe-POMs.FePMo displayed the highest visible light absorption,the largest specific surface area,the most sensitive photocurrent response and the smallest charge transfer resistance,which were all beneficial for heterogeneous photocatalysis.The efficiency for Cr(VI)reduction was ca.88%by FePMo after 50 min visible light irradiation.The estimated rate constant(0.042 min^-l)was ca.2.5 and 1.8 times that by FePW and FeSiw.respectively.FTIR spectra indicated that the Keguin structure of PMoOag was maintained inFePMo.Mechanism study indicated that the photogenerated electrons in LUMO and the holes in HOMO were thermo-dynamically feasible for Cr(VI)reduction and H20 oxidation,respectively.Using FePMo as an optimized photocatalyst.good stability was also observed after 5 cvclic runs in both photocatalvtic performance and XRD structure. | CEN Qing XIAO Wei LIU Yingqi WANG Qi NAFADY Ayman MA Shengqian | 2020 | Chemical Research in Chinese Universities2020，36，6： | 1 |

| 12 | Utilization of cationic microporous metal-organic framework for efficient Xe/Kr separation显示文摘The separation of xenon/krypton(Xe/Kr)mixtures plays a vital role in the industrial process of manufacturing high-purity xenon.Compared with energy-intensive cryogenic distillation,porous materials based on physical adsorption are very promising in the low-cost and energy-saving separation processes.Herein,we show that a cationic metal-organic framework(named as FJU-55)exhibits highly efficient Xe/Kr separation performance,which can be attributable to its uniform three-dimensional(3D)interconnection channels and the electro-positive features as the host framework.Moreover,FJU-55 demonstrates good Xe adsorption capacity of 1.41 mmol/g and excellent Xe/Kr selectivity of 10(298 K and 100 kPa),together with a high Qst value of 39.4 kJ/mol at low coverage area.The superior Xe/Kr separation performance of FJU-55 was further confirmed by the dynamic breakthrough experiments.Results obtained via molecular modeling studies have revealed that the suitable pore size and abundant accessible aromatic ligands in FJU-55 could offer strong multiple C–H∙∙∙Xe interactions,which play a collaborative role in this challenging gas separation task. | Lingshan Gong Ying Liu Junyu Ren Abdullah MAl-Enizi Ayman Nafady Yingxiang Ye Zongbi Bao Shengqian Ma | 2022 | Nano Research2022，15，8： | 1 |

| 18 | Converging Cooperative Functions into the Nanospace of Covalent Organic Frameworks for Efficient Uranium Extraction from Seawater显示文摘The extraction of uranium from seawater is challenging though it offers tremendous potential for the sustainable production of nuclear fuel for the energy sector.Herein,we report a new strategy for efficient extraction of uranium from seawater via converging the cooperative functions of adsorption-photocatalysis into the nanospace of covalent organic frameworks(COFs).Functionalization of the organic linkers in the multicomponent COFs allowed exploration of the relationship between material composition and adsorption-photocatalytic activity for uranium extraction.The presence of amidoxime groups in the COFs offered selective binding sites for uranyl,whilst triazine units and bipyridine-Pd groups acted cooperatively to photocatalytically reduce adsorbed U(Ⅵ)to a U(Ⅳ)solid product(UO2)for facile collection.One of our developed COFs,4-Pd-AO,displayed exceptional performance in sequestering and reducing uranyl from natural seawater,with a high extraction capacity of 4.62 mg U/g per day(average data)under visible light irradiation.Mechanistic studies revealed that 4-Pd-AO not only reduced adsorbed uranyl(Ⅵ)to U(Ⅳ)O_(2),but also generated ^(1)O_(2) and superoxide radicals under visible light excitation,thus affording excellent antibacterial and antialgal activities(i.e.,antibiofouling properties)for sustained efficient uranium extraction performance.This proof-ofconcept study establishes multicomponent COFs as promising candidates for efficient uranium extraction from seawater. | Mengjie Hao Zhongshan Chen Xiaolu Liu Xianhai Liu Juyao Zhang Hui Yang Geoffrey I.N.Waterhouse Xiangke Wang Shengqian Ma | 2022 | CCS Chemistry2022，4，7： | 1 |
| 19 | Bionic Thermosensation Inspired Temperature Gradient Sensor Based on Covalent Organic Framework Nanofluidic Membrane with Ultrahigh Sensitivity显示文摘The ability to precisely monitor temperature at a high resolution is an important task,particularly in terms of safety.Inspired by natural thermosensitive transient receptor potential cation channels,we developed a temperature sensor based on thermaldriven ionic charge separation.To mimic the function of nature,an ionic covalent organic frameworkbased nanofluidic membrane was fabricated.By engineering the membrane to separate two electrolyte solutions,the temperature difference across the membrane can synchronously induce a potential.The high charge density and narrow channel size render extraordinary permselectivity to the membrane,thus offering a thermosensation selectivity of up to 1.25 mV K^(−1),superior to that of any known natural system.Additionally,the generated potential is linearly related to the introduced temperature gradient,thus allowing for precise detection.With these attributes,an alarm device with high thermosensation sensitivity was constructed,demonstrating great promise for environmental temperature monitoring. | Weipeng Xian Pengcheng Zhang Changjia Zhu Xiuhui Zuo Shengqian Ma Qi Sun | 2021 | CCS Chemistry2021，3，11： | 1 |
