ABSTRACT:
A multifunctional material having a carbon-doped titanium oxide layer, which has carbon doped in the state of Ti—C bonds, is excellent in durability (high hardness, scratch resistance, wear resistance, chemical resistance, heat resistance) and functions as a visible light responding photocatalyst, is provided. The multifunctional material of the present invention is obtained, for example, by heat-treating the surface of a substrate, which has at least a surface layer comprising titanium, a titanium alloy, a titanium alloy oxide, or titanium oxide, in a combustion gas atmosphere of a gas consisting essentially of a hydrocarbon such that the surface temperature of the substrate is 900 to 1,500° C.; or by directly striking a combustion flame of a gas consisting essentially of a hydrocarbon, against the surface of the substrate for heat treatment such that the surface temperature of the substrate is 900 to 1,500° C.
