VISIBLE-LIGHT RESPONSE PHOTOCATALYST AND PHOTOLYSIS METHOD OF ENVIRONMENTAL POLLUTANT

摘要

PROBLEM TO BE SOLVED: To provide a catalytic activity improver capable of supplying a photolytic action of a visible-light response photocatalyst and improving its photocatalytic activity, to provide a visible-light response photocatalyst to be used with the catalytic activity improver together, and to provide an effective photolysis method of an environmental pollutant using the visible-light response photocatalyst.;SOLUTION: A Pd compound is supported on a W compound by a kneading method or a wet-type preparation method to give the visible-light response photocatalyst. The visible-light response photocatalyst, in which the W compound is tungsten oxide, is provided. The visible-light response photocatalyst, which is powder or porous thin-film like, is provided. The photolysis method of the environmental pollutant, using the visible-light response photocatalyst, is provided.;COPYRIGHT: (C)2009,JPO&INPIT
