| Research Abstract |
Many efforts have been devoted to synthesis of photocatalysts that respond to visible light. This study explored new application of surface plasmon resonance (SPR) of gold (Au) nanoparticles as plasmonic photocatalysts working under irradiation of visible light. The plasmonic photocatalysts exhibited unique photoabsorption properties and photocatalytic performances in the minerarization of organic acid, selective oxidation, H2 formation, and reduction of organic compounds under irradiation of visible light. The functionalized SPR photocatalysts with platinum, silver and palladium co-catalysts worked effectively in H2 formation, reduction of nitrobenzene and dechlorination of chlorobenzene, respectively. The results introduced in this study can be widely applied for design and development of new plasmonic photocatalysts exhibiting further excellent activities and selectivities.
