ZIRCONIUM OXIDE-BASED OPTICALLY FUNCTIONAL OXIDE

摘要

PROBLEM TO BE SOLVED: To provide a new zirconium oxide-based optically functional oxide having sensibility to visible light, its manufacturing method and its product.

SOLUTION: The optically functional oxide consists of the crystalline metallic compound shown by general formula: (ZrO2)1-n[(M1O5/2)(M2O3/2)]n(wherein M1is at least one metallic element selected from Nb, Ta and Sb; M2is at least one metallic element selected from Cr and Fe). The method for manufacturing the optically functional oxide comprises a solution precipitation reaction step. A photocatalytic product consists of the optically functional oxide. The optically functional oxide can be used as a new zirconium oxide-based photocatalyst which can be used in a visible light region accounting for the majority of solar energy and has excellent sensibility to visible light.
