摘　　要：在电解水产氢技术的研究中,与贵金属基催化材料相比,高效、低成本的钴基催化剂引起了研究者的极大兴趣。传统单一功能的钴基催化剂虽然在析氢反应(HER)或析氧反应(OER)中表现出良好的催化性能,但限制了电解水技术的发展,相比之下,钴基双功能催化剂因其实用性和降低电解槽制备成本备受关注。总结了目前报道的钴基双功能催化剂中常见的钴基氧化物、钴基氮化物、钴基磷化物、钴基硫化物催化剂,综述了对钴基双功能催化剂不足采取的改进和优化方法,对未来催化剂的制备提供了借鉴意义。In the research of electrolytic hydrogen production technology,cobalt based catalysts with high efficiency and low cost have attracted great interest from researchers compared to precious metal based catalytic materials.Although traditional single function cobalt based catalysts exhibit good catalytic performance in hydrogen evolution reaction(HER)or oxygen evolution reaction(OER),they limit the development of electrolysis water technology.In contrast,cobalt based bifunctional catalysts have attracted much attention due to their practicality and ability to reduce the preparation cost of electrolysis cells.This article summarizes the commonly reported cobalt based bifunctional catalysts,including cobalt based oxides,cobalt based nitrides,cobalt based phosphides,and cobalt based sulfides.It describes the improvement and optimization methods adopted by people to address the shortcomings of such catalysts,providing reference for the preparation of cobalt based bifunctional catalysts in the future.
