Abstract

An unreported nanometer TiO₂ photocatalyst doped with upconversion luminescence agent (40CdF₂ · 60BaF₂ · 0.8Er₂O₃) utilizing visible light was prepared. Its photocatalytic activity was checked through the photocatalytic degradation of acid red B as a model compound under visible light irradiation. Results show that the upconversion luminescence agent prepared as dopant can effectively turn visible lights to ultraviolet lights, which can be absorbed by nanometer TiO₂ particles to produce the electron-cavity pairs. Therefore, the photocatalytic ability of this novel TiO₂ photocatalyst has greatly been enhanced compared with undoped and common TiO₂ photocatalyst.
