| 1 | Boride-based electrocatalysts:Emerging candidates for water splitting显示文摘Electrocatalytic water splitting(EWS)is a promising route to produce hydrogen in a sustainable and environment-benign manner.To realize the large-scale hydrogen production,it is paramount to develop desirable electrocatalysts with engineered structure,high catalytic activity,facile accessibility,low cost,and good durability.Of late,boride-based materials,especially transition-metal borides(TMBs),are emerging as promising candidates for the EWS process.However,so far,ittle attempt has been made to provide a comprehensive summary on these findings.Herein,this review provides the up-to-date status on upgrading the catalytic performance of TMB-based nanomaterials by regulating the internal and external characteristics.The conventional synthetic techniques are first presented for the preparation of TMB-based catalysts.Afterwards,the advanced strategies are summarized to enhance the catalytic performance of TMBs,including morphology control,component regulation,phase engineering,surface oxidation and hybridization.Then,the design principles of TMB-based electrocatalysts for high-performance EWS are outined.Lastly,the current challenges and future directions in the development of TMB-based materials are proposed.This review article is expected to envisage insights into the TMBs-based water splitting and to provide strategies for design of the next-generation TMB-based electrocatalysts. | ZhiJie Chen Xiaoguang Duan Wei Wei Shaobin Wang Zejie Zhang Bing-Jie Ni | 2020 | Nano Research2020，13，2： | 5 |
| 2 | Carbon-based single atom catalyst: Synthesis, characterization, DFT calculations显示文摘Carbon-based single-atom catalysts(SACs) with atomic sizes of active sites have become the promising candidates for a variety of catalytic systems because of their high atom utilization, and unique electronic structures. Different types of single-atom sites can be fabricated via multiple preparation strategies, which would demonstrate distinct different coordination configurations and electronic features, and ultimately affected the structure-catalysis relationship of SACs in targeted reactions. As a result, it is necessary to identify the active sites of SACs and understand the structure-catalysis relationship of SACs at the atomic scale. In this review, a variety of preparation strategies of carbon-based SACs were documented. Then, the recent development on versatile characterization techniques and computational achievements were summarized regarding in understanding the electronic and geometric characteristics of carbon-based SACs.Finally, major challenges and development directions concerning single-atom sites identification and advanced tools development are discussed to shed light on future research of carbon-based SACs. | Yanan Shang Xiaoguang Duan Shaobin Wang Qinyan Yue Baoyu Gao Xing Xu | 2022 | Chinese Chemical Letters2022，33，2： | 2 |
| 3 | Boron carbide boosted Fenton-like oxidation: A novel Fe(Ⅲ)/Fe(Ⅱ) circulation显示文摘The sluggish kinetics of Fe(Ⅱ)recovery in Fenton/Fenton-like reactions significantly limits the oxidation efficiency.In this study,we for the first time use boron carbide(BC)as a green and stable promotor to enhance the reaction of Fe(Ⅲ)/H_(2)O_(2) for degradation of diverse organic pollutants.Electron paramagnetic resonance analysis and chemical quenching/capturing experiments demonstrate that hydroxyl radicals(·OH)are the primary reactive species in the BC/Fe(Ⅲ)/H_(2)O_(2) system.In situ electrochemical analysis indicates that BC remarkably boosts the Fe(Ⅲ)/Fe(Ⅱ)redox cycles,where the adsorbed Fe(Ⅲ)cations were transformed to more active Fe(Ⅲ)species with a higher oxidative potential to react with H_(2)O_(2) to produce Fe(Ⅱ).Thus,the recovery of Fe(Ⅱ)from Fe(Ⅲ)is facilitated over BC surface,which enhancesOH generation via Fenton reactions.Moreover,BC exhibits outstanding reusability and stability in successive cycles and avoids the secondary pollution caused by conventional organic and metalliferous promotors.Therefore,metal-free BC boosting Fe(Ⅲ)/H_(2)O_(2) oxidation of organics provides a green and advanced strategy for water decontamination. | Peng Zhou Feng Cheng Gang Nie Yangyang Yang Kunsheng Hu Xiaoguang Duan Yongli Zhang Shaobin Wang | 2020 | Green Energy & Environment2020，5，4： | 2 |
| 4 | Active sites and reaction mechanism for N-doped carbocatalysis of phenol removal显示文摘Heteroatom-doping of carbocatalysts has been a powerful strategy to remarkably enhance the catalytic performance.Herein,the underlying nature of N promotional effects on peroxymonosulfate(PMS)activation for phenol removal is understood by combining kinetics analysis with multiple techniques.A strategy using mixed acid oxidation of carbon nanotube(CNT)followed by NH3 treatment is employed to yield a series of catalysts with different N-doping contents but similar fraction of sp^(2)-hybridized carbon and defective degree,endowing with a chance to discriminate the dominant N-containing active sites.The multi-sites kinetics analysis suggests the graphitic N-containing sites as the dominant active sites.The mechanism of the surface-bound reactive species is also discriminated as the dominant reaction mechanism.The insights reported here could provide the methodology to fundamentally understand the heteroatom-doping effects of carbocatalysis. | Mingjie Zhang Chen Han Wenyao Chen Wei Luo Yueqiang Cao Gang Qian Xinggui Zhou Xiaoguang Duan Shaobin Wang Xuezhi Duan | 2020 | Green Energy & Environment2020，5，4： | 1 |

| 6 | Direct-acting Antiviral-induced Transient Recovery of NK Cells in Early-stage Treatment of Chronic Hepatitis C Patients显示文摘Background and Aims:The rapid clearance of hepatitis C virus induced by direct-acting antivirals(DAAs)affects natural killer(NK)cells,but the reported results are not consistent,and the relative mechanism was unclear.This study focused on the dynamic changes of NK cells during and after DAA treatment and analyzed the reasons.Meth-ods:Peripheral blood from 35 chronic hepatitis C patients who were treated with DAAs were collected at baseline and weeks 1,2,4,12,and post-treatment week-12.The fre-quency,subset,and phenotype of NK cells were assayed by flow cytometry.Lactate dehydrogenase assays were used to evaluate the cytotoxicity of NK cells.Cytokine concentra-tions were measured with Luminex kits.Results:All pa-tients achieved a sustained viral response(SVR),and the NK cell frequencies were not changed significantly during DAA therapy.However,the cytotoxicity of NK cells recov-ered significantly early in week 1,and then continuously decreased below normal levels.The changes of genotypes including NKp30+,NKp46+,and NKG2A+NK cells were par-allel to NK function.The subset of CD56dim NK cells con-tinuously increased and did not return to normal even at 12 weeks after treatment.Interleukin(IL)-2,IL10,IL15,interferon-gamma,and tumor necrosis factor-alpha all in-creased after week 4,peaked at the end of therapy,and then exhibited varying degrees of reduction with time.Con-clusions:DAA treatment led to transient functional recov-ery of NK cells in the early stage of treatment,and then continuously decreased to below normal levels.Alterations of NK subsets,phenotypes,and the microenvironment may be involved in the changes. | Xiaohui Zhang Yingying Jiang Shaobin Li Dandan Bian Mei Liu Ming Kong Yu Chen Zhongping Duan Sujun Zheng | 2022 | Journal of Clinical and Translational Hepatology2022，10，6： | 0 |
| 7 | Two-dimensional nanomaterials confined single atoms: New opportunities for environmental remediation显示文摘Two-dimensional(2D)supports confined single-atom catalysts(2D SACs)with unique geometric and electronic structures have been attractive candidates in different catalytic applications,such as energy conversion and storage,value-added chemical synthesis and environmental remediation.However,their environmental appli-cations lack of a comprehensive summary and in-depth discussion.In this review,recent progresses in synthesis routes and advanced characterization techniques for 2D SACs are introduced,and a comprehensive discussion on their applications in environmental remediation is presented.Generally,2D SACs can be effective in catalytic elimination of aqueous and gaseous pollutants via radical or non-radical routes and transformation of toxic pollutants into less poisonous species or highly value-added products,opening a new horizon for the contami-nant treatment.In addition,in-depth reaction mechanisms and potential pathways are systematically discussed,and the relationship between the structure-performance is highlighted.Finally,several critical challenges within this field are presented,and possible directions for further explorations of 2D SACs in environmental remediation are suggested.Although the research of 2D SACs in the environmental application is still in its infancy,this review will provide a timely summary on the emerging field,and would stimulate tremendous interest for designing more attractive 2D SACs and promoting their wide applications. | Yu Yin Lei Shi Shu Zhang Xiaoguang Duan Jinqiang Zhang Hongqi Sun Shaobin Wang | 2023 | Nano Materials Science2023，5，1： | 0 |
| 8 | van der Waals type II carbon nitride homojunctions for visible light photocatalytic hydrogen evolution显示文摘Photocatalytic hydrogen evolution reaction(PC-HER)provides a solution to energy crisis and environmental pollution.Herein,different graphitic carbon nitride(g-C_(3)N_(4))-based van der Waals(vdW)type II homojunctions have been fabricated and g-C_(3)N_(4)/Kdoped g-C_(3)N_(4)nanosheets have an outstanding PC-HER rate of 1,243μmol·h^(−1)·g^(−1)under visible light,higher than that of bulk g-C_(3)N_(4),doped g-C_(3)N_(4)nanosheets,and mixed nanosheets.The enhanced PC-HER performance can be ascribed to the cooperative effects of the shortened bandgap,enlarged specific surface area,matched type II energy band structure,“face to face”vdW charge interaction,and peculiarly partite positions of the conduction and valence bands in different layers.Besides,the type II junctions were found superior to binary type II junction.This study highlights the synergistic effect of different strategies in improving the PC-HER capacities of g-C_(3)N_(4),especially the application of particular vdW junctions,and provides new insights to the structures and mechanism. | Xiaojie Li Panpan Zhang Huayang Zhang Wenjie Tian Yangyang Yang Kunsheng Hu Dechao Chen Qin Li Xiaoguang Duan Hongqi Sun Shaobin Wang | 2023 | Nano Research2023，16，4： | 0 |
| 9 | Intrinsic Mechanisms of Morphological Engineering and Carbon Doping for Improved Photocatalysis of 2D/2D Carbon Nitride Van Der Waals Heterojunction显示文摘Van der Waals(VDW)heterojunctions in a 2D/2D contact provide the highest area for the separation and transfer of charge carriers.In this work,a top-down strategy with a gas erosion process was employed to fabricate a 2D/2D carbon nitride VDW heterojunction in carbon nitride(g-C_(3)N_(4))with carbon-rich carbon nitride.The created 2D semiconducting channel in the VDW structure exhibits enhanced electric field exposure and radiation absorption,which facilitates the separation of the charge carriers and their mobility.Consequently,compared with bulk g-C_(3)N_(4)and its nanosheets,the photocatalytic performance of the fabricated carbon nitride VDW heterojunction in the water splitting reaction to hydrogen is improved by 8.6 and 3.3 times,respectively,while maintaining satisfactory photo-stability.Mechanistically,the finite element method(FEM)was employed to evaluate and clarify the contributions of the formation of VDW heterojunction to enhanced photocatalysis,in agreement quantitatively with experimental ones.This study provides a new and effective strategy for the modification and more insights to performance improvement on polymeric semiconductors in photocatalysis and energy conversion. | Jinqiang Zhang Xiaoli Zhao Lin Chen Shuli Li Haijun Chen Yuezhao Zhu Shuaijun Wang Yang Liu Huayang Zhang Xiaoguang Duan Mingbo Wu Shaobin Wang Hongqi Sun | 2023 | Energy & Environmental Materials2023，6，3： | 0 |
| 10 | Electron transfer to direct oxidation of aqueous organics by perovskites显示文摘The residual of oxidant chemicals in advanced oxidation processes(AOPs)resulted in both economic cost and secondary pollution.Herein,we report a direct oxidation of phenolic pollutants induced by Ca-Mn-O perovskites without using an oxidant.Governed by one-electron transfer process(ETP)from the phenolics to the Ca-Mn-O perovskites,this direct oxidation proceeds in fast reaction kinetics with activation energy of 51.4 kJ/mol,which was comparable with those AOPs-based catalytic systems.Additionally,mineralization and polymerization reactions occurred on the Ca-Mn-O surface and ensured the complete removal of phenolics.The high spin state Mn(III)within Ca-Mn-O structure was the dominant active site for this ETP.The elongated axial Mn(III)–O bonds within the[MnO_(6)]octahedron facilitated the acceptance of the electrons from the phenolics and thus promoted the initiation of the direct oxidation process.Mn(III)in the high spin state can also activate dissolved O_(2)to produce singlet oxygen(^(1)O_(2))for a fast removal of phenolics.The mixed Mn(III)/Mn(IV)within Ca-Mn-O accelerated the ETP by enhancing the electrical conductivity.This efficient Ca-Mn-O-induced ETP for removal of organic contaminants casts off the dependence on external chemical and energy inputs and provides a sustainable approach for transforming the toxic organic pollutants into value-added polymers. | Tao Kong Yuxian Wang Shenning Liu Ya Liu Menghan Zhou Bofeng Li Xiaoguang Duan Chunmao Chen Shaobin Wang | 2023 | Nano Research2023，16，5： | 0 |
