摘要：
TiO2 nanotube arrays were fabricated by electrochemical anodic oxidation method, then ZnO nanoparticles were deposited on the surface of TiO2 nanotube by optical chemical deposition technique to get ZnO/TiO2 nanocomposites. Samples were characterized by Raman and XRD spectroscopies, and SEM. The photoelectrochemical performance of the samples was estimated by testing their open circuit photo-potential vs time (OCPT) and photocurrent vs time (I-t). It was found that the deposition of ZnO nanoparticle didn't change the crystalline phase of TiO2; photoelectric performance of TiO2 nanotube was enhanced by combined with ZnO nanoparticles and the sample fabricated by immerging TiO2 nanotube in 10(-3) mol.L-1 Zn(NO3)(2) aqueous solution displayed optimal photoelectric performance.
