摘　　要：大规模制氢的迫切需求推动了对低廉、高效和稳定的电解水催化剂的大量研究。研究表明,硒化物和硫化物的化学性质不仅非常相似,且过渡金属(Fe, Co, Ni, Mo, Cu等)硒化物对析氢和析氧具有良好的催化作用。近年来,为了取代贵金属及其衍生物,一些报告提出了各种各样的方法来增强硒化镍(Ni_(x)Se_(y))基催化剂的电催化活性。综述了Ni_(x)Se_(y)基电催化剂用于HER、OER和整体水分解的最新进展。从界面、缺陷、晶体结构和组成方面论述了Ni_(x)Se_(y)基电催化剂的优点和局限性。展望了电解水催化剂的发展前景和未来面临的挑战。The urgent need for large-scale hydrogen production has led to extensive research on low-cost,efficient and stable water splitting catalysts.Studies have shown that the chemical properties of selenides and sulfides are not only very similar,but also transition metal(Fe,Co,Ni,Mo,Cu,etc.)selenides have good catalytic effects on hydrogen and oxygen evolution.In recent years,in order to replace noble metals and their derivatives,some reports have proposed various methods to enhance the electrocatalytic activity of nickel selenide(Ni_(x)Se_(y))-based catalysts.This paper reviews the latest progress of Ni_(x)Se_(y)-based electrocatalysts for HER,OER and overall water splitting.The advantages and limitations of Ni_(x)Se_(y)-based electrocatalysts are discussed from the aspects of interface,defects,crystal structure and composition.In addition,we highlight new strategies and future challenges for the design and synthesis of high-performance electrocatalysts.
