Nanoscaled TiO2 photocatalyst has attracted much more attention due to its stable chemical and physical property,lower cost and excellent photocatalytic performance.[1,2] However,the broad bandgap of TiO2 seriously restrains its practical application in the area of full-wavelength of solar spectrum.Recently,Ti3+ self-doped TiO2 was reported to exhibit high visible light absorption and considerable photochemistry performance.
