Abstract

Titania/nitrogen-doped titania (TiO2/TiO2-xN y) composite was prepared by mechanical milling in liquid medium and the phase composition, specific surface area, photo chemical properties, and photocatalytic activities were characterized. TiO2/TiO 2-xNy composites showed excellent photocatalytic ability for the oxidative destruction of nitrogen monoxide and acetaldehyde. It is suggested that the doped nitrogen in TiO2-xNy acts as the acceptor of photoinduced holes on TiO2/TiO2 to depress the recombination of the electron-hole and improve the photocatalytic activity.
