Surface plasmon resonance-enhanced solar-driven photocatalytic performance from Ag nanoparticles-decorated Ti3+ self-doped porous black TiO2 pillars

Ag decorated Ti3+ self-doped porous black TiO2 pillars are fabricated via oil bath method, combined with wet-impregnation and surface hydrogenation and exhibit excellent solar-driven photocatalytic performance, which is ascribed to enhanced photoresponse to visible/near-infrared and spatial separation of photogenerated charge carriers, increased active sites, and efficient surface plasma resonance.
