CARBON-DOPED TITANIUM OXIDE AND ITS PRODUCING METHOD, PHOTOCATALYST, AND METHOD OF OXIDIZING ORGANIC COMPOUND BY USING THE CATALYST

摘要

PROBLEM TO BE SOLVED: To provide a titanium oxide doped with another element showing a high catalytic activity even in a visible light at a long wavelength side and its producing method and a photocatalyst with a high activity.

SOLUTION: The carbon-doped titanium oxide is a titanium oxide doped with carbon. Preferably, the carbon atom is doped as a carbon ion. The carbon-doped titanium oxide is produced by calcining a mixture of a titanium compound having oxygen atoms and a carbon source. In the presence of a photocatalyst composed of the carbon-doped titanium oxide, an organic compound having a part to be oxidized is oxidized with a molecular oxygen or a peroxide under an irradiation of light.
