The TiO2 nanorods decorated graphene sheets (TNGS) are fabricated via a facile non-hydrolytic sol�gel approach. Various analytical methods confirmed that the TiO2 nanorods are well-dispersed and successfully anchored on the graphene surface by covalently bond. In addition, photocatalytic activities are performed by varying the weight ratio of graphene oxide and TiO2 in the view point of the efficiencies of photodecomposition and adsorption of methylene blue. The as-synthesized TNGS showed unprecedented photodecomposition efficiency compared to the pristine TiO2 nanorods and the commercial P25 under visible light. It is believed that this predominant photocatalytic activity is due to the synergistic contribution of both a retarded charge recombination rate caused by the high electronic conductive graphene and an increased surface area originated from nanometer-sized TiO2 nanorods. Furthermore, photoelectrochemical study is performed to give deep insights into their roles in the photocatalytic reaction .
