Electrocatalytic water splitting to produce hydrogen is an eco-friendly way to achieve sustainable utilization of renewable energy.The industrial application of water electrolysis,which is severely limited by slow kinetic reactions on electrode surfaces,requires the development of highly reactive,low-cost and stable electrocatalytic materials.Transition metal borides/borates have re-cently emerged as promising electrocatalytic materials for catalyzing hydrogen/oxygen evolution reactions(HER/OER)in inexpensive electrolyzers.However,so far,there has been little compre-hensive summary of transition metal borides/borates.Here,this review provides the latest research progress on transition metal borides/borates for electrocatalytic water splitting.The structural characteristics of transition metal borides/borates and their synthesis methods in recent years are discussed.Then,the theoretical and experimental progress of transition metal borides including single-metal borides,multi-metal borides,borate derived and other nanocomposites containing boron(boron-doped nanocomposites/substrate with boron)in electrocatalytic reaction and the role of boron in regulating electrocatalytic performance are further emphasized.Finally,the potential challenges and future prospects of transition metal borides/borates in electrocatalysis are presented.
