発明の名称 (英語) PHOTOCATALYST PARTICLE AND METHOD FOR PRODUCING SAME, MATERIAL INCLUDING SAID PARTICLE, AND PRODUCT INCLUDING SAID MATERIAL NEW
発明の概要(英語) The present invention relates to: a photocatalyst particle and a method for producing the same, the photocatalyst particle including a titanium dioxide, phosphorus, silver, a silver oxide, and a silver phosphate; a material including said photocatalyst particle; and a product including said material.
従来技術、競合技術の概要(英語) BACKGROUND ART
In recent years, titanium dioxide photocatalyst action (TiO2), water and air purification has been received much attention in the art (for example, Non-Patent Document 1, reference 2). However, for example, an electronic, a fast recombination of a pair of holes, an oxidation-reduction reaction by the visible light (photocatalytic reaction) not shown, the separation of the titanium dioxide nanoparticles is very time consuming problem, the second inhibiting practical use of the titanium oxide (for example, see Non-Patent Document 3-5). In particular, the conventional titanium dioxide photocatalyst system, an oxidation-reduction reaction by the irradiation of ultraviolet light to the one shown, the visible light irradiation in the oxidation-reduction reaction is not shown, only the sunlight is not a sufficient photocatalytic activity. Therefore, the photocatalyst is used in the prior art, ultraviolet light is irradiated to the photocatalyst when the light source for the problem that it requires.
Patent Document 1 in which, between the metal silver, silver phosphate and titanium dioxide nano-particles and the photocatalyst is disclosed. Photocatalyst disclosed in this document, the visible light photocatalyst activity.
