Abstract

By using an oxygen vacancy (Ov)-enriched TiO₂ surface, herein we report a photo-induced activation process of Pt-deposited TiO₂ (Pt/V-TiO₂) for its photocatalytic application. The Ov-related photo-induced modulation of Pt nanoparticles is realized, with which the average size of Pt nanoparticles decreases from 2.65 to 1.82 nm and a more active Pt⁰ component is generated.
