摘　　要：电解水制氢具有操作简单、高效环保等优点,被认为是最具发展潜力的制氢方式,但通常需要施加较大的过电位才能达到工业电解水所需的电流密度。为了降低过电位,减少非必要的能量损失,亟需开发高性能、低成本的析氢反应(HER)电催化剂。钙钛矿材料储量丰富、价格低廉、结构灵活多变,已成为一类用于HER的新型非贵金属基电催化剂。本文首先对HER的基本机理进行了介绍,重点论述了钙钛矿氧化物在电催化HER领域的研究进展,讨论并分析了提升HER性能的策略(离子掺杂、异质结构构筑、形貌结构调控等),最后提出了钙钛矿型HER电催化剂所面临的挑战,并展望了其研究前景。Electrochemical water splitting,a highly-efficient and environment-friendly technology has been considered as one of the most promising methods for hydrogen production.However,a large overpotential is generally required to achieve the current density for industrial water electrolysis.As a result,it is highly desirable to develop high-performance and cost-effective hydrogen evolution reaction(HER)electrocatalysts for the widespread application of water splitting.Perovskite oxides have emerged as a new category of nonprecious metal catalysts for electrocatalytic HER due to their low cost,abundant compositions and flexible structures.In this review,the HER mechanism in alkaline environment is briefly elaborated.Then,the research progress of perovskite oxides in HER is reviewed.Moreover,the strategies(ion doping,heterostructure engineering,morphology and structure regulation,etc.)for promoting HER performance are discussed and analyzed.Finally,the remaining challenges faced by perovskite HER electrocatalysts and the future prospects are put forward.
