In both heterogeneous catalysis and emerging electrocatalysis, the interfacial synergy between metal and supporting metal oxide, plays a vital role to determine the active sites and promote the catalytic reaction through cooperativity and multifunctionality.  Conventionally, such interface is usually fabricated through either in situ growth or direct assembly of metal nanoparticles onto oxides, providing limited interfacial effects. In this talk, we will discuss how to precisely synthesize and tailor metal-oxide interface through a controllable surface segregation strategy and how to understand its catalytic role in conversion of small molecules, such as CO, H2O2, etc.
