Abstract

Abstract: When gold is deposited as nanoparticles (NPs) with mean diameters of 2–5 nm or clusters with mean diameters below 2 nm onto a variety of supports such as metal oxides, carbons, polymers, etc., the supported Au NPs exhibit unique catalytic properties, while bulk Au is almost inert as a catalyst. A lot of research works indicate that the key factors of the catalysis by supported Au NPs are the selection of the supports, the control of the Au NP size, the shape of the Au NPs, and the strong junction between Au NPs and the supports, because the perimeter zone around Au NPs acts as the active site for many reactions. In order to elucidate the origin of catalysis by supported Au NPs, the interplay between physicochemical analysis, computational studies, and rational experiments for catalysis by supported Au NPs is becoming more and more important. This article summarizes our experiences and progress in such interplay. Abstract : Au nanocluster catalysts exhibit remarkable catalytic activities for several reactions. The emphasis here is on our research into the development of preparation methods, their characterization, theoretical calculations, and application in catalysis. We share our insight into the interplay between them.
