XRD, DRS, EDX, SEM and HRTEM results confirmed that the carbon in the sample existed as free carbon (C-C), carbonate carbon (-CO3) and doped into lattice of TiO2(Ti-C), resulting in red shift of optical adsorption edge and band gap narrowing. The photo activity of the C-doped TiO2, tested on 2-chlorophenol, revealed that it was more active under visible light (kvis= 3.50 x 10-3 min-1).
