Surface plasmon resonance-enhanced visible-light-driven photocatalysis by Ag nanoparticles decorated S-TiO2−x nanorods

Plasmonic Ag decorated S-TiO2−x nanorods with narrow bandgap are fabricated via a facile calcination, in-situ solid-state chemical reduction combined with photo-deposition approach, and exhibit excellent visible-light-driven photocatalytic performance, which is ascribed to the synergistic effects of surface plasmon resonance of Ag nanoparticles, S doping and Ti3+self-doping.111
