In this study, a novel so-called “gel–sol” process isfirstly reported for synthesis of TiO2nanorod (TN)
combining reduced graphene oxide (RGO) composites. By utilizing the triethanolamine (TEOA) as shape
controller and under specific conditions (such as pH?12), the hybrid composites can be readily obtained.
The higher pH value benefits the deprotonation of TEOA for adsorption to the stationary nuclei.
Therefore, the synthesized hybrid composites have the morphology of crystalline anatase TiO2nanorods
anchored into the surface of reduced graphene oxide. The hybrid composites fabricated by the novel
process have distinct advantages over the traditional methods for obtaining TiO2and graphene-based
composites in terms of the well-confined TiO2morphology and the formation of Ti–C bonds between TN
and RGO simultaneously.
