Title:
炭素ドープ酸化チタンとその製造法、光触媒、及び該触媒を用いた有機化合物の酸化方法
Document Type and Number:
Japanese Patent JP4526273
Kind Code:
B2
Abstract:

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.

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.
