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

5Density Functional Theory for Electrocatalysis显示文摘It is a considerably promising strategy to produce fuels and high-value chemicals through an electrochemical conversion process in the green and sustainable energy systems.Catalysts for electrocatalytic reactions,including hydrogen evolution reaction(HER),oxygen evolution reaction(OER),oxygen reduction reaction(ORR),nitrogen reduction reaction(NRR),carbon dioxide reduction reaction(CO_(2)RR),play a significant role in the advanced energy conversion technologies,such as water splitting devices,fuel cells,and rechargeable metal-air batteries.Developing low-cost and highly efficient electrocatalysts is closely related to establishing the composition-structure-activity relationships and fundamental understanding of catalytic mechanisms.Density functional theory(DFT)is emerging as an important computational tool that can provide insights into the relationship between the electrochemical performances and physical/chemical properties of catalysts.This article presents a review on the progress of the DFT,and the computational simulations,within the framework of DFT,for the electrocatalytic processes,as well as the computational designs and virtual screenings of new electrocatalysts.Some useful descriptors and analysis tools for evaluating the electrocatalytic performances are highlighted,including formation energies,d-band model,scaling relation,egorbital occupation,and free energies of adsorption.Furthermore,the remaining questions and perspectives for the development of DFT for electrocatalysis are also proposed.Xiaobin Liao Ruihu Lu Lixue Xia Qian Liu Huan Wang Kristin Zhao Zhaoyang Wang Yan Zhao 2022Energy & Environmental Materials2022,5,1:2
6Tunable Ru-Ru2P heterostructures with charge redistribution for efficient pH-universal hydrogen evolution显示文摘Designing synergistic heterogeneous catalytic interfaces is the key to developing highly compatible pH-universal electrocatalysts for complex chemical environments.Our theoretical calculation results demonstrate that the Ru-Ru2P heterointerface can not only promote the redistribution of charges,but also reduce the d-band center,and then enhances the adsorption capacity of the key intermediate.However,in situ and facile synthesis of Ru-Ru2P heterostructures is severely limited by thermodynamic obstacles.Herein,we propose a molten salt-assisted catalytic synthesis scheme,and successfully build a series of homologous metallic Ru-Ru2P heterostructure catalysts with different molar ratios of Ru to P under atmospheric pressure and low-temperature(400C).The resultant Ru-Ru2P with rich heterostructures show the Pt-like HER performance in different pH media.Particularly,it is prominent under alkaline conditions(18 mV@10 mA cm^(2)),which outperforms the Pt catalyst(37 mV@10 mA cm^(2)).Furthermore,Ru-Ru2P heterostructures also show certain potential in the electrolysis of seawater to produce hydrogen.This work represents a significant supplement of high-efficiency pH-universal HER catalysts,and provides a new light on interface engineering in energy technology fields and beyond.Ding Chen Ruohan Yu Ruihu Lu Zonghua Pu Pengyan Wang Jiawei Zhu Pengxia Ji Dulan Wu Jinsong Wu Yan Zhao Zongkui Kou Jun Yu Shichun Mu 2022InfoMat2022,4,5:2
7Epitaxially Grown Ru Clusters-Nickel Nitride Heterostructure Advances Water Electrolysis Kinetics in Alkaline and Seawater Media显示文摘The epitaxial heterostructure can be rationally designed based on the in situ growth of two compatible phases with lattice similarity,in which the modulated electronic states and tuned adsorption behaviors are conducive to the enhancement of electrocatalytic activity.Herein,theoretical simulations first disclose the charge transfer trend and reinforced inherent electron conduction around the epitaxial heterointerface between Ru clusters and Ni_(3)N substrate(cRu-Ni_(3)N),thus leading to the optimized adsorption behaviors and reduced activation energy barriers.Subsequently,the defectrich nanosheets with the epitaxially grown cRu-Ni_(3)N heterointerface are successfully constructed.Impressively,by virtue of the superiority of intrinsic activity and reaction kinetics,such unique epitaxial heterostructure exhibits remarkable bifunctional catalytic activity toward electrocatalytic OER(226 mV@20 mA cm^(−2))and HER(32 mV@10 mA cm^(−2))in alkaline media.Furthermore,it also shows great application prospect in alkaline freshwater and seawater splitting,as well as solar-to-hydrogen integrated system.This work could provide beneficial enlightenment for the establishment of advanced electrocatalysts with epitaxial heterointerfaces.Jiawei Zhu Ruihu Lu Wenjie Shi Lei Gong Ding Chen Pengyan Wang Lei Chen Jinsong Wu Shichun Mu Yan Zhao 2023Energy & Environmental Materials2023,6,2:2

9Coordination environments tune the activity of oxygen catalysis on single atom catalysts:A computational study显示文摘Designing highly efficient bifunctional electrocatalysts for oxygen reduction and evolution reaction(ORR/OER)is extremely important for developing regenerative fuel cells and metal-air batteries.Single-atom catalysts(SACs)have gained considerable attention in recent years because of their maximum atom utilization efficiency and tunable coordination environments.Herein,through density functional theory(DFT)calculations,we systematically explored the ORR/OER performances of nitrogencoordinated transition metal carbon materials(TM-N_(x)-C(TM=Mn,Fe,Co,Ni,Cu,Pd,and Pt;x=3,4))through tailoring the coordination environment.Our results demonstrate that compared to conventional tetra-coordinated(TM-N_(4)-C)catalysts,the asymmetric tri-coordinated(TM-N_(3)-C)catalysts exhibit stronger adsorption capacity of catalytic intermediates.Among them,Ni-N_(3)-C possesses optimal adsorption energy and the lowest overpotential of 0.29 and 0.28 V for ORR and OER,respectively,making it a highly efficient bifunctional catalyst for oxygen catalysis.Furthermore,we find this enhanced effect stems from the additional orbital interaction between newly uncoordinated d-orbitals and p-orbitals of oxygenated species,which is evidently testified via the change of d-band center and integral crystal orbital Hamilton population(ICOHP).This work not only provides a potential bifunctional oxygen catalyst,but also enriches the knowledge of coordination engineering for tailoring the activity of SACs,which may pave the way to design and discover more promising bifunctional electrocatalysts for oxygen catalysis.Gaofan Xiao Ruihu Lu Jianfeng Liu Xiaobin Liao Zhaoyang Wang Yan Zhao 2022Nano Research2022,15,4:1

15Metalloporphyrin-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
