Description | In this study, to improve the photocatalytic reactivity of TiO2 and to extend its light absorption into
the visible light region, nitrogen (N) and fluorine (F) doped TiO2 and some Perovskite-type LaTiO2+xN1-x were synthesized. The photocatalytic activity of N,F-doped TiO2 under not only visible irradiation but also UV irradiation exceeded that of commercial anatase type TiO2 (ST-01 by Ishihara Sangyo, Ltd.). This high photocatalytic activity under LED irradiation is indispensable to development of photocatalytic environmental purification process. Some Perovskite-type LaTiO2+xN1-x with anion nonstoichiometry were prepared by heating an oxide precursor under ammonia atmosphere and successively annealed under diluted ammonia. Increasing O/N ratio enhances the optical bandgap of the oxynitrides. A series of perovskite-type LaTiO2N materials with compositions a slightly deviated from the stoichiometric metal composition was also prepared. Increasing Ti/La ratio results in deterioration of reflectivity. |
