Preparations and Photocatalytic Properties of Visible-Light-Active Nitrogen-Doped TiO₂

Abstract:

A visible-light-active N-TiO₂ photocatalyst was prepared by a simple method: TiN nanoparticles were calcined in the O₂/N₂ atmosphere. The prepared N-TiO₂ shows high photocatalytic activity for the degradation of methyl orange in water under visible light irradiation. The photodegradation results indicate that the prepared photocatalysts have the best photocatalytic activity when TiN was calcined at 650 °C for 15 min in the O₂/N₂ atmosphere with 1:15 (volume) of O₂/N₂.
