CONTROLLABLE HYDROTHERMAL SYNTHESIS AND MORPHOLOGY EVOLUTION OF TiO2 NANOROD FILMS

TiO2 nanorod films with diverse and evolutionary morphologies are synthesized by controllable hydrothermal method under mild conditions. The as-prepared nanorod films are well characterized by X-ray diffraction, scanning electron microscopy and atomic force microscopy. Results demonstrate that reasonable control of time of secondary growth could easily and conveniently achieve the goal of morphology adjustment during mild condition hydrothermal synthesis process.
