Abstract
This review summarizes the utilization of supported noble metal nanoparticles such as Au/TiO2 Au/ZrO2 Ag/AgCl as efficient photo/sonocatalysts for the selective synthesis of chemicals and degradation of environmental pollutants Supported noble metal nanoparticles could efficiently catalyze the conversion of solar energy into chemical energy Under UV/visible light irradiation important chemical transformations such as the oxidation of alcohols to carbonyl compounds the oxidation of thiol to disulfide the oxidation of benzene to phenol and the reduction of nitroaromatic compounds to form aromatic azo compounds are effectively achieved by supported noble metal nanoparticles Under ultrasound irradiation supported noble metal nanoparticles could efficiently catalyze the production of hydrogen from water Moreover various pollutants including aldehydes alcohols acids phenolic compounds and dyes can be effectively decomposed over supported noble metal nanoparticles under UV/visible light irradiation Under ultrasound irradiation pollutant molecules can also be completely degraded with supported noble metal nanoparticles as catalysts
