摘要

Owing to the distinctive structural and electronic properties,atomically dispersed metal catalysts have raised tremendous attentions in the last ten years [1,2].Generally,isolated metal atoms or clusters that dispersed across oxide supports (e.g.,Al2O3,TiO2,CeO2) are stabilized through the coordination with supported O atoms,forming electrondeficient metal cations (Mδ+-O) at interfaces [3].However,in many cases,such metal-support interactions may not strong enough to maintain their structure uniformity under harsh reductive conditions,and the resultant reduction/aggregation of metal atoms/clusters often attenuated the activity of catalysts [4,5].
