Au catalysis is representative of nanocatalysis. Au catalysis has been demonstrated to be very complex and structure-sensitive. In this short review we summarize the literature reports on Au catalysis and our recent progress on the fundamental understanding of Au catalysis using model catalysts from single crystals to nanocrystals. We demonstrate the structure-sensitivity of Au catalysis used for NO decomposition, CO oxidation, and propylene epoxidation with H2 and O2 and the corresponding active Au structures. We discuss the effects of the geometric and electronic structures and the Au–oxide support interactions on Au catalysis, and the origin of high catalytic activity of the Au surface at low temperatures. Finally, we provide an outlook for future research directions of structure-sensitive Au catalysis.
