    Nanosized C-doped TiO2 was prepared by a new method based on resorcinol-formaldehyde (RF) gel formation in situ during hydrolysis of Ti precursor (TTIP, titanium tetraisopropoxide). 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).
