Abstract

Abstract : Electronic metal‐support interaction (EMSI) strongly modifies electronic structures of both metal nanoparticles and supported oxides. By designing and investigating cerium oxides/Ag inverse catalysts, it was found that Ag cubes enclosed by the {001} facets with a smaller work function exert a stronger EMSI effect on the CeO x overlayers than Ag cubes enclosed by the {111} facets, and only the CeO2 overlayers with a fully developed bulk CeO2 electronic structure significantly promote the catalytic activity of Ag nanocrystals in CO oxidation, whereas cerium oxide overlayers with other electronic structures do not. The cover image illustrates that the capability of the transferring electrons plays a crucial role to the EMSI. More information can be found in the Communication by W. Huang, et al. on page 15978 .
