摘　　要：燃料电池和金属-空气电池是一类清洁、高效的能源利用装置。为了实现碳中和生态经济,燃料电池和金属-空气电池将有望成为未来的重要能源利用方式之一。氧还原反应(ORR)和析氧反应(OER)是这两类能源利用装置最重要的两个反应。因此,提高燃料电池和金属-空气电池催化效率是提高它们能源利用率的重要手段。从简化、降低成本和系统实际应用的角度来看,在同一电解系统中实现ORR和OER催化剂的耦合是可行的。在这方面,镍元素是催化ORR和OER最有效的双功能元素。本文对镍基化合物双功能催化剂的研究现状进行了综述,并指出了双功能催化剂的研究发展方向。Fuel cells and metal-air cells are a kind of clean and efficient energy utilization devices.In order to achieve a carbon neutral ecological economy,fuel cells and metal-air cells are expected to be one of the important energy utilization methods in the future.Oxygen reduction reaction(ORR)and oxygen evolution reaction(OER)are the two most important reactions in these two types of energy utilization devices.Therefore,improving the catalytic efficiency of fuel cells and metalair cells is an important means to improve their energy efficiency.From the point of view of simplification,cost reduction and practical application of the system,it is feasible to realize the coupling of ORR and OER catalyst in the same electrolysis system.In this regard,nickel is the most effective bifunctional element for catalyzing ORR and OER.In this paper,the research status of bifunctional catalysts for nickel-based compounds is reviewed,and the development direction of bifunctional catalysts is pointed out.
