可視光応答性光触媒

Document Type and Number:

Japanese Patent JP4997627

Kind Code:

B2

Abstract:

To respond to such a request that a material having an activity equal to or higher than that of titanium oxide, that of doped titanium oxide or that of an existing visible light-responsive photocatalyst is obtained from oxide materials of easily available materials.

A photocatalyst, which has excellent photocatalytic characteristics even when irradiated with visible light and the photocatalytic activity higher than that of AgNbO3being one of visible light-responsive materials, is obtained by forming a solid solution satisfying the composition shown by the general formula: AgxM1-xTi1-xNbxO3(wherein M is one or more metals selected from bivalent metals consisting of Mg, Ca, Sr, Ba and Zn; and x is a numerical value satisfying 0.05≤x<1) from AgNbO3and MTiO3.
