Abstract
Sr4Ti3O10, which is known to have a Ruddlesden-Popper phase as a layered perovskite-type oxide, showed activity leading to the decomposition of pure water into H2 and O2 without any co-catalyst, when irradiated with light under 395 nm. When NiO x was loaded onto Sr4Ti3O10 both by the impregnation (I) method and the vapor deposition (VD) method, this photocatalytic activity drastically increased. Nickel acetylacetonate, when used with the VD method, was found to give rise to more efficient photocatalytic activity than that obtained using nickel nitrate with the impregnation method.
