| 1 | Unlocking the door to highly efficient Ag-based nanoparticles catalysts for NaBH4-assisted nitrophenol reduction显示文摘Ag-based nano particles(NPs)catalysts have recently attracted in creasi ng atte ntion in NaBH4-assisted n itrophe nol reducti on,especially in 4?n itrophe nol(4?NP)reducti on.Moreover,Ag-based NPs catalysts are con sidered to be very promising for practical applicati ons because of their fascinating advantages,e.g.,easy preparation,relatively low cost and less toxicity,high activity and good stability.Basically,the size and shape of Ag NPs are well known as the key factors for achieving highly efficient catalytic reduction of 4-NP.In this review,three highly efficient Ag-based NPs catalysts(supported Ag NPs,anisotropic Ag NPs and bimetallic Ag NPs)are highlighted for the 4-NP reduction,in eluding the catalytic mecha nism and reactio n rate caused by their adjustments in size and shape.Although high catalytic activity has bee n demonstrated by several Ag-based NPs catalysts,further improvement in the catalytic performance is still desired.In terms of the most recent progress in Ag-based NPs catalysts for 4?NP reduction,this review provides a comprehensive assessment on the material selection,synthesis and catalytic characterizations of these catalysts.Moreover,this review aims to correlate the catalytic performance of Ag-based NPs catalysts with their size and shape,guiding the development of novel cost-effective and high-performance catalysts. | Guangfu Liao Yan Gong Liu Zhong Jiasheng Fang Li Zhang Zushun Xu Haiyang Gao Baizeng Fang | 2019 | Nano Research2019，12，10： | 9 |
| 2 | Process and challenges of stainless steel based bipolar plates for proton exchange membrane fuel cells显示文摘Proton exchange membrane fuel cell(PEMFC)powered automobiles have been recognized to be the ultimate solution to replace traditional fuel automobiles because of their advantages of PEMFCs such as no pollution,low temperature start-up,high energy density,and low noise.As one of the core components,the bipolar plates(BPs)play an important role in the PEMFC stack.Traditional graphite BPs and composite BPs have been criticized for their shortcomings such as low strength,high brittleness,and high processing cost.In contrast,stainless steel BPs(SSBPs)have recently attracted much attention of domestic and foreign researchers because of their excellent comprehensive performance,low cost,and diverse options for automobile applications.However,the SSBPs are prone to corrosion and passivation in the PEMFC working environment,which lead to reduced output power or premature failure.This review is aimed to summarize the corrosion and passivation mechanisms,characterizations and evaluation,and the surface modification technologies in the current SSBPs research.The non-coating and coating technical routes of SSBPs are demonstrated,such as substrate component regulation,thermal nitriding,electroplating,ion plating,chemical vapor deposition,and physical vapor deposition,etc.Alternative coating materials for SSBPs are metal coatings,metal nitride coatings,conductive polymer coatings,and polymer/carbon coatings,etc.Both the surface modification technologies can solve the corrosion resistance problem of stainless steel without affecting the contact resistance,however still facing restraints such as long-time stability,feasibility of low-cost,and mass production process.This paper is believed to enrich the knowledge of high-performance and long-life BPs applied for PEMFC automobiles. | Gaoyang Liu Faguo Hou Shanlong Peng Xindong Wang Baizeng Fang | 2022 | International Journal of Minerals,Metallurgy and Materials2022，29，5： | 4 |
| 3 | Electrochemical behavior and electrowinning of palladium in nitric acid media显示文摘In this study,the electrochemical behavior of Pd(II)in nitric acid media was investigated using various electrochemical techniques.By analyzing the cyclic voltammogram of Pd(II)recorded at Pt electrode,a series of electrochemical reactions associated with palladium were recognized,indicating that Pd(II)undergoes a single step two-electrons irreversible process.Electroreduction reaction of Pd(II)and auto-catalytic reactions of nitrous acid are supposed to play a leading role in low and high concentrations of nitric acid,respectively.Stirring could facilitate the reduction of Pd(II)in relatively low nitric acid concentration(3 mol/L).The value of charge transfer coefficient was determined to be 0.18 for the measurements at 298 K.The diffusion coefficient of Pd(II)increased from 1.89×10 8cm2/s at 288 K to 4.23×10 8cm2/s at 318 K,and the activation energy was calculated to be 21.5 kJ/mol.In electrowinning experiments,SEM images of palladium obtained by electrolysis reveal the dendrite growth in all cases,which is uniform all over the entire surface of Pt electrode.The recovery ratios of Pd at different nitric acid concentrations are high,and the faradic efficiency of electrolysis decreases with increasing the nitric acid concentration.When stirring was introduced during electrolysis,the electrodeposition rate of Pd increased substantially. | LIU ShengChu WEI YueZhou LIU RuiQin FANG BaiZeng | 2013 | Science China Chemistry2013，56，12： | 3 |
| 4 | Mechanism for nucleation and growth of electrochemical deposition of palladium(II) on a platinum electrode in hydrochloric acid solution显示文摘Palladium(II)and chloride ions tend to form complexes in aqueous solution.Both theoretical and experimental(by UV spectrum)results indicate that there are four complexes formed in aqueous solution containing 3 mol/L hydrochloric acid and 20mmol/L PdCl2.This work evaluates the kinetics of electrochemical deposition of palladium on a Platinum electrode.For this purpose,palladium electrodeposition was investigated by means of cyclic voltammetry(CV),potentiostatic current-time transients(CTTs)and Tafel curve.By CTTs curves,the regions corresponding to the charge transfer control,mixed control and diffusion control were identified.In the diffusion control region,palladium electrodeposition mechanism was characterized as progressive nucleation with three-dimensional(3D)growth under diffusion control;as for the mixed control region,an adsorption(IAds),ion transfer(IIT),and nucleation and growth(ING)model were proposed to analyze the current-time transients quantitatively,which could separate the IAds,IIT and ING perfectly. | GU Shuai WANG XinPeng WEI YueZhou FANG BaiZeng | 2014 | Science China Chemistry2014，57，5： | 2 |

| 11 | Low-cost fabrication of highly dispersed atomically-thin MoS2 nanosheets with abundant active Mo-terminated edges显示文摘In this work,highly dispersed atomically-thin MoS2 nanosheets were fabricated at one thousandth of the commercial cost using sepiolite(SEP)mineral nanofibers as carriers via a microwave hydrothermal method.Atomresolved microscopy revealed the MoS2 nanosheets were only 1–4 atomic layers thick.The Mo atoms anchored on the mineral surface served as nucleation sites for the nanosheet growth.The MoS2 layers were in staggered stacking yielding abundant atomic steps at the nanosheets’edges,where catalytically active molybdenum terminations dominated instead of the inert sulfur atoms commonly reported.DFT calculations disclosed that the bonding of Mo(MoS2)and O(SEP)at the MoS2/sepiolite(MSEP)interface enabled SEP to be a unique support,superior to the other minerals for growing such highly-dispersed ultrathin MoS2 architecture.In a typical photocatalyisis application,the MSEP demonstrated a significantly improved photocatalytic performance for RhB degradation compared with the MoS2 nanosheets assembled microspheres.This work provides an important new strategy for low-cost batch preparation of high quality 2D materials via assembly on mineral materials. | Fei Wang Ming Hao Wei Liu Penji Yan Baizeng Fang Sijia Li Jinsheng Liang Maomao Zhu Li Cui | 2021 | Nano Materials Science2021，3，3： | 0 |
| 12 | An Approach towards Synthesis of Nanoarchitectured LiNi1/3Co1/3Mn1/3O2 Cathode Material for Lithium Ion Batteries显示文摘To explore advanced cathode materials for lithium ion batteries(LIBs),a nanoarchitectured LiNi_(1/3)Co_(1/3)Mn_(1/3)O_(2)(LNCM)material is developed using a modified carbonate coprecipitation method in combination with a vacuum distillation-crystallisation process.Compared with the LNCM materials produced by a traditional carbonate copre-cipitation method,the prepared LNCM material synthesized through this modified method reveals a better hexago-nal layered structure,smaller particle sizes(ca.110.5 nm),and higher specific surface areas.Because of its unique structural characteristics,the as-prepared LNCM material demonstrates excellent electrochemical properties in-cluding high rate capability and good cycleability when it is utilized as a cathode in the lithium ion battery(LIB). | Weibo Hua Yanjie Wang Yanjun Zhong Guoping Wang Benhe Zhong Baizeng Fang Xiaodong Guo Shixuan Liao Haijiang Wang | 2015 | Chinese Journal of Chemistry2015，33，2： | 0 |
