摘　　要：与单金属原子催化剂相比,双金属原子催化剂可以打破反应中间体的吸附能和协同效应的比例关系,在燃料电池相关反应具有良好的活性。本文阐述了用于电催化反应的PdAu双金属催化剂的合成方法以及PdAu双金属催化剂的不同结构对性能的影响,并综述了PdAu双金属催化剂用于燃料电池相关反应(包括氧还原反应、甲醇氧化反应、乙醇氧化反应和甲酸氧化反应)的最新研究进展,最后提出了PdAu双金属催化剂存在的不足并对在燃料电池中高效利用的未来方向提出了个人观点。Compared with single metal atom catalysts(SACs),bimetallic atom catalysts can break the proportional relationship between the adsorption energy of reaction intermediates and the synergistic effect,and have good activity in fuel cell related reactions.This paper describes the synthesis of PdAu bimetallic catalysts for electrocatalytic reactions and the influence of different structures of PdAu bimetallic catalysts on their performance,and reviews the recent research progress of PdAu bimetallic catalysts for fuel cell related reactions including oxygen reduction reaction(ORR),methanol oxidation reaction(MOR),ethanol oxidation reaction(EOR)and formic acid oxidation reaction(FAOR).Finally,the shortcomings of PdAu bimetallic catalysts are presented and the future direction of efficient utilization in fuel cells was discussed.
