C, F-codoped TiO2 nanoobjects with anatase phase were synthesized by calcination of a mixture of TiOF2 and sulfuric-acid-treated melamine. The C, F co-doping resulted in a red-shift of the absorption edge to 510 nm from the 390-nm value obtained for a control TiO2 photocatalyst. The C, F-codoped TiO2 shows photocatalytic activity under visible light irradiation. Furthermore, the loading of AgCl into the parent co-doped TiO2 enhanced its activity for degradation of methylene blue dye by about 3.5 times in the first hour irradiation. A brief mechanism responsible for the enhancement is proposed in terms of the transfer of holes from C, F-codoped TiO2 to the AgCl phase. (c) 2013 Elsevier B.V. All rights reserved.
