Preparation of TiO2/CNT Composites and Effect of CNT's Structure on Morphology of Nano-TiO2
Abstract:
Four kinds of TiO2/CNT (or carbon fiber) composites were successfully prepared by the sol-gel method using Ti(OBu)4 as precursor of TiO2, and untreated CNT, carboxylic CNT, hydroxylated CNT and carbon fiber were used as carriers, respectively. After heat treatment at 400 and 800°C, TiO2/CNT nanocomposites and purified TiO2 were obtained. Their structure and morphology were characterized by X-ray diffraction (XRD) and scanning electron microscope (SEM). The results indicate that different carbon nanotubes and nanofiber have notable influences on the morphology and structure of TiO2 nanocrystals.
