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.
