| 英文摘要 | Plasmonic metal Ag nanoparticles (AgNPs) on TiO2 thin films (AgNPs/TiO2) are a kind of excellent photocatalyst of high efficiency under visible light, and thus draw great interest nowadays. Further improvement of their photocatalytic activity (PA) is difficult but is of high importance for their applications. In this paper, oxygen plasma was taken to partially oxidize AgNPs deposited on the surface of TiO2 to form a structure with the configuration of a p-type semiconductor/plasmonic metal/n-type semiconductor (Ag2O/AgNPs/TiO2). The localized surface plasmon resonance (LSPR) of the AgNPs was strongly damped after oxygen plasma irradiation (OPI) but the photocatalytic activity was improved. The mechanisms of the photocatalytic activity improvement under UV and visible light were explored based on charge kinetics. |
