| 1 | High-entropy alloys and compounds for electrocatalytic energy conversion applications显示文摘High-entropy materials,composed of five or more elements in near-equiatomic percentage,have been attracting tremendous interests due to their advantageous properties in a variety of applications.Recently,electrocatalysis on high-entropy alloys(HEAs)and high-entropy compounds(HECs)has emerged as a new and promising material owing to the tailored composition and the disordered con-figuration of HEAs and HECs.Though extensive efforts have been devoted to investigating the catalytic nature of HEAs and HECs,the details related to the active sites and intrinsic activity of such catalysts still remain uncertain due to the complexity of the multicomponent systems.In this review,the recent progress of HEAs and HECs is systematically reviewed in terms of their synthetic strate-gies and electrocatalytic applications.Importantly,the computationally assisted methods(e.g.,density functional theory[DFT])are also presented to discover and design the optimumHEA-andHEC-based catalysts.Subsequently,the appli-cations of HEAs and HECs in electrocatalytic energy conversion reactions will be discussed,including hydrogen evolution reaction,oxygen evolution reaction,oxygen reduction reaction,carbon dioxide reduction reaction,nitrogen reduction reaction,methanol oxidation reaction,and ethanol oxidation reaction(EOR).Moreover,the prospects and future opportunities for this research field are cau-tiously discussed.A series of upcoming challenges and questions are thoroughly proposed from the experimental and theoretical aspects as well as other future applications in electrocatalysis. | Hang Liu Lenus Syama Like Zhang Carmen Lee Chuntai Liu Zhengfei Dai Qingyu Yan | 2021 | SusMat2021，1，4： | 1 |
| 2 | Interface and M^(3+)/M^(2+)Valence Dual-Engineering on Nickel Cobalt Sulfoselenide/Black Phosphorus Heterostructure for Efficient Water Splitting Electrocatalysis显示文摘The catalyst innovation that aims at noble-metal-free substitutes is one key aspect for future sustainable hydrogen energy deployment.In this paper,a nickel cobalt sulfoselenide/black phosphorus heterostructure(NiCoSe|S/BP)was fabricated to realize the highly active and durable water electrolysis through interface and valence dual-engineering.The NiCoSe|S/BP nanostructure was constructed by in-situ growing NiCo hydroxide nanosheet arrays on few-layer BP and subsequently one-step sulfoselenization by SeS2.Besides the conductive merit of BP substrate,holes in p-type BP are capable of oxidizing the Co^(2+)to high-valence and electron-accepting Co^(3+),benefiting the oxygen evolution reaction(OER).Meanwhile,Ni^(3+)/Ni^(2+)ratio in the heterostructure is reduced to maintain the electrical neutrality,which corresponds to the increased electron-donating character for boosting hydrogen evolution reaction(HER).As for HER and OER,the heterostructured NiCoSe|S/BP electrocatalyst exhibits small overpotentials of 172 and 285 mV at 10 mA cm^(-2)(η_(10))in alkaline media,respectively.And overall water splitting has been achieved at a low cell potential of 1.67 V at η_(10) with high stability.Molecular sensing and density functional theory(DFT)calculations are further proposed for understanding the rate-determine steps and enhanced catalytic mechanism.The investigation presents a deep-seated perception for the electrocatalytic performance enhancement of BP-based heterostructure. | Tingting Liang Syama Lenus Yaoda Liu Ya Chen Thangavel Sakthivel Fuyi Chen Fei Ma Zhengfei Dai | 2023 | Energy & Environmental Materials2023，6，2： | 0 |
