1Recent advances in non-precious metal electrocatalysts for pH-universal hydrogen evolution reaction显示文摘Hydrogen production by water electrolysis is a compelling technology to produce fuels and chemicals powered by renewable energy.It is highly desirable to develop cost-effective and durable electrocatalysts for hydrogen evolution reaction(HER).This review has summarized recent progress in mechanism understanding of non-precious metal electrocatalysts for pH-universal HER.The general approaches have been demonstrated to overcome the activity/stability limitations of the electrocatalysts for HER in a broad pH range.The perspectives and challenges for the development of p H-universal HER electrocatalysts have also been proposed.This review sheds light on the design and fabrication of high-performance electrocatalysts for versatile HER-related energy technologies.Shen Zhang Xing Zhang Yuan Rui Ruihu Wang Xiaoju Li 2021Green Energy & Environment2021,6,4:4

9Metalloporphyrin-based covalent organic frameworks composed of the electron donor-acceptor dyads for visible-light-driven selective CO2 reduction显示文摘The visible-light-driven photocatalytic CO2 reduction with high efficiency is highly desirable but challenging.Herein,we present porphyrin-tetraphenylethene-based covalent organic frameworks(MP-TPE-COF,where M=H2,Co and Ni;TPE=4,4′,4″,4?-(ethane-1,1,2,2-tetrayl)tetrabenzaldehyde;COF=covalent organic framework)as ideal platforms for understanding photocatalytic CO2 reduction at molecular level.Experimental and theoretical investigations have demonstrated crucial roles of metalloporphyrin units in selective adsorption,activation and conversion of CO2 as well as in the separation of charge carriers and electron transfer,thus allowing for flexible modulation of photocatalytic activity and selectivity.Co P-TPE-COF exhibits high CO evolution rate of 2,414μmol g-^1 h^-1 with the selectivity of 61%over H2 generation under visible-light irradiation,while Ni P-TPE-COF provides CO evolution rate of 525μmol g^-1 h^-1 and 93%selectivity with superior durability.Moreover,the photocatalytic system is feasible for the simulated flue gas,which provides CO evolution rate of 386μmol g-1 h-1 and selectivity of 77%.This work provides in-depth insight into the structure-activity relationships toward the activation and photoreduction of CO2.Haowei Lv Rongjian Sa Pengyue Li Daqiang Yuan Xinchen Wang Ruihu Wang 2020Science China Chemistry2020,63,9:1

12Exploring the growth mechanism of CuSbSe_(2)thin film prepared by electrodeposition显示文摘Copper antimony selenium(CuSbSe_(2))has advantages of adjustable band gaps from 1.09 eV to 1.2 eV,high light absorption coefficient(>105 cm-1),and low grain generation temperature(300—400℃),which is suitable for the preparation of solar cells.However,the stable range of CuSbSe_(2)(CASe)phase is narrow,which is inevitable to form Sb_(2)Se_(3)and Cu_(3)SbSe_(4)second phase during the preparation process.In this work,selenization annealing of Sb/Cu metal layer to prepare CASe thin films with pulse electrodeposition process was studied,and the growth mechanism of CASe film was analyzed.Cu and Sb reacted with Se to form Cu_(2)Se and Sb_(2)Se_(3),respectively.Then Cu_(2)Se and Sb_(2)Se_(3)further reacted to generate CASe.Since the formation temperature of Cu_(3)SbSe_(4)was lower than that of CASe,the preferential formation of Cu_(3)SbSe_(4)led to layer separation.When the annealing temperature was too high,CASe decomposed to form Cu_(3)SbSe_(3)and Sb_(2)Se_(3).Additionally,by increasing the heating rate,the separation of CASe thin films was effectively improved,and the CASe thin films with relatively high crystallinity were obtained at 360℃with heating rate of 30℃/min and selenization time of 20 min.WANG Ruihu BI Jinlian LI Wei YUAN Yujie XING Yupeng YAO Liyong 2023Optoelectronics Letters2023,19,9:0
13Defense against local model poisoning attacks to byzantine-robust federated learning显示文摘1 Introduction As a new mode of distributed learning,Federated Learning(FL)helps multiple organizations or clients to jointly train an artificial intelligence model without sharing their own datasets.Compared with the model trained by each client alone,a high-accuracy federated model can be obtained after multiple communication rounds in FL.Due to the characteristics of privacy protection and distributed learning,FL has been applied in many fields,such as the prognosis of pandemicdiseases,smartmanufacturing systems,etc.Shiwei LU Ruihu LI Xuan CHEN Yuena MA 2022Frontiers of Computer Science2022,16,6:0

15Dynamic reconstruction of Ni-Zn alloy solid-electrolyte interface for highly stable Zn anode显示文摘Aqueous zinc ion batteries(AZIBs)are ideal candidates for large-scale battery storage,with a high theoretical specific capacity,ecological friendliness,and extremely low cost but are strongly hindered by zinc dendrite growth.Herein,Ni-Zn alloy is artificially constructed as a solid-electrolyte interface(SEI)for Zn anodes by electrodeposition and annealing.The Ni-Zn alloy layer acts as a dynamic shield at the electrode/electrolyte interface.Interestingly,the zinc atoms migrate out of the electrode body during zinc stripping while merging into the electrode body during the plating.In this way,the Ni-Zn alloy is able to guide the zinc deposition in the horizontal direction,thereby suppressing the formation of dendrite.Benefiting from those,the Ni-Zn alloy symmetric cell shows a greatly improved cycle life and is able to operate stably for 1,900 h at a current density of 0.5 mA·cm^(−2).The present study is a strategy for negative electrode protection of AZIBs.Qian Zhang Yuhang Dai Kangning Zhao Chengyi Zhang Ruihu Lu Jinghao Li Shuhan Jin Lei Zhang Qinyou An Liqiang Mai 2023Nano Research2023,16,9:0
16Facile fabrication of ultrafine nickel-iridium alloy nanoparticles/graphene hybrid with enhanced mass activity and stability for overall water splitting显示文摘Developing active and durable electrocatalysts for overall water splitting is desirable but challenging to realize sustainable hydrogen production.Here,we report a facile and general method to prepare ultrafine nickel(Ni)-iridium(Ir)alloy nanoparticles/graphene hybrids for overall water splitting.The optimized hybrid with 4.9 wt%Ir exhibits much higher catalytic activity and durability than commercial 20 wt%Ir/C for both oxygen evolution reaction(OER)and hydrogen evolution reaction(HER).Theoretical simulations reveal that the incorporation of Ir in metallic Ni lattice regulates hydrogen adsorption free energy to the optimum level,thus improving HER activity,while in situ generated amorphous Ir-Ni hydr(oxy)oxides around metallic Ni-Ir core have been demonstrated to be the active species under OER conditions,which switches OER rate-determining step to energy-favorable pathway.The overall water splitting electrolyzer assembled by the optimized electrocatalyst shows a low cell voltage of only 1.52 V and excellent stability to deliver a current density of 10 m A cm-2.This work provides a powerful strategy toward general synthesis of ultrafine alloy nanoparticles for high-performance overall water splitting.Shen Zhang Xing Zhang Xuerong Shi Feng Zhou Ruihu Wang Xiaoju Li 2020Journal of Energy Chemistry2020,29,10:0
