Abstract

Gold catalysis play an important role in environmental catalysis, conversion of petroleum products, and energy catalysis. The majority of gold catalysts are prepared by loading gold nanoparticles on metal oxide supports, such as TiO2. Here we show that using conventional deposition-precipitation, gold nanoparticles can also be successfully assembled on salts, such as a series of commercialized metal phosphates. The catalysts were characterized by BET, XRD, ICP-OES, and TEM. The gold particles prove to be small, only several nanometers. Most importantly, some of these catalysts showed high activity in CO oxidation around room temperature, and selective CO oxidation in the presence of H2. Further research on the application of these catalysts in other reactions are in progress.
