Title:
RUTILE TITANIUM DIOXIDE NANOPARTICLES EACH HAVING NOVEL EXPOSED CRYSTAL PLANE AND METHOD FOR PRODUCING SAME
Document Type and Number:
WIPO Patent Application WO/2011/016329
Kind Code:
A1
Abstract:
Disclosed are: novel rutile titanium dioxide nanoparticles which have high photocatalytic activity; a photocatalyst which is composed of the rutile titanium dioxide nanoparticles; and a method for oxidizing an organic compound, wherein the photocatalyst is used. The rutile titanium dioxide nanoparticles are characterized by having an exposed crystal plane (001). The rutile titanium oxide nanoparticles are able to be produced by subjecting a titanium compound to a hydrothermal treatment in an aqueous medium in the presence of a hydrophilic polymer. A polyvinylpyrrolidone or the like is used as the hydrophilic polymer. An organic compound having a moiety to be oxidized can be oxidized by a molecular oxygen or a peroxide by being irradiated with light in the presence of a photocatalyst that is composed of the rutile titanium oxide nanoparticles.
