Abstract

Layered K-Fe-Ti metal oxide, a new kind of photocatalyst was obtained via a solid-state reaction route with the mixture of KNO3, Fe(NO3)3·9H2O, TiO2. The effects of preparing parameters such as material ratio and reaction temperature etc, on the structure characteristics and crystal morphology
were investigated by using XRD, SEM and TEM technology. Meanwhile, under UV light irradiation, the native photocatalyst was found to evolve H2 from pure water. The result indicates that not only the photocatalyst prepared has high photocatalytic activity, but aslo its visible light absorption is notable with comparison of that by using market TiO2.

Key words： layered metal oxide; solid-state reaction; photocatalytic
