Abstract
A photocatalyst with visible light activity in which TiC is supported at least partially on a surface of TiO2 is claimed. This is obtained by subjecting TiO2 to a CVD treatment in a plasma with a mixed gas of hydrocarbon and methane. A method for decomposing material wherein a material to be decomposed such as formaldehyde is made in contact with the above-mentioned catalyst to which light including at least visible ray is radiated. According to the present invention, a photocatalyst with visible light activity capable of making harmless organic compounds such as formaldehyde, a method for making harmless organic compounds such as formaldehyde by the use of the photocatalyst and a method for photo-decomposition of organic compounds such as tar are provided.
