摘　　要：合金纳米颗粒(NPs)由于多金属之间的协同效应使其具有优异的催化性能、抗积碳和抗硫毒化性能,被广泛应用于固体氧化物燃料电池(SOFC)阳极。NPs在还原气氛下从氧化物支撑体内原位析出,提升了纳米催化剂稳定性的同时使支撑体内富含氧空位,进一步提升阳极的电子电导率和离子电导率。NPs的优异催化性能使SOFC可以碳氢化合物为燃料并具备长期工作稳定性成为可能。主要综述了合金催化剂在SOFC阳极中的发展现状并据此提出了展望。Alloy nanoparticles(NPs)have been widely used in the anodes of solid oxide fuel cells(SOFCs)because of their excellent catalytic performances and high resistances to coke deposition and H2S.These unique properties mainly originate from the synergistic effect between different metals.In-situ preparation of NPs from parent oxides in reducing atmosphere can produce supported metal nanoparticles with high stability and parent oxides with high oxygen vacancies,which improves the electronic and ionic conductivities of anodes.The excellent catalytic performance of alloy catalysts makes it possible for SOFCs to take hydrocarbon as fuel and operate stably and durably.The trends and advances in metal alloy nanoparticles applied to the anodes of SOFCs are summarized and the prospects for further studies in this field are proposed.
