英文摘要	a pd single-atom alloy (saa) structure was constructed by alloying pd with au supported on silica. the xrd and hrtem results demonstrated that the addition of a small amount of pd efficiently prevented the sintering of au nanoparticles. the drifts and exafs results confirmed that the pd saa structure was formed when the atomic ratios of pd/au were lower than 0.025. the pd saa structure exhibits a much better catalytic performance for the selective hydrogenation of acetylene in excess ethylene than the corresponding monometallic au or pd systems.
