| Summary: | Supported Au nanoparticles have been extensively investi- gated in heterogeneous catalysis since the seminal work of Haruta＇s research group, in part because of their high activity in some reactions, especially CO oxidation [1-5]. Although many studies have been performed, two problems still remain： aggregation of Au nanoparticles and their catalytic reaction mechanism. Many strategies have been developed to increase Au nanoparticle stability, such as modification of metal nanoparticle composition, metal-support interfaces, and support nanostructures [6-9]. However, Au particles prepared by the deposition-precipitation method are usually larger than 2 nm. Au nanoparticles smaller than 2 nm easily aggregate, and how to stabilize them is an interesting topic. In addition, many studies on the reaction mechanism catalyzed by supported Au nanoparticles have been performed, but the conclusions are not in agreement. This is mainly because of the heterogeneous distribution of the active metal in the catalysts, which |
