| 摘 要： | 采用电化学阳极氧化法制备TiO2纳米管,然后用光化学沉积法在TiO2纳米管表面沉积ZnO纳米颗粒制备ZnO/TiO2纳米复合材料。对样品进行了Raman谱、XRD和SEM表征,通过测定光电流-时间(I-t)和开路电压-时间(OCPT)曲线对ZnO/TiO2纳米复合材料的光电化学性能进行研究。结果表明,沉积ZnO没有改变TiO2的相结构;复合ZnO提高了TiO2的光电性能;在Zn(NO3)2浓度为10-3 mol.L-1的条件下制得的ZnO/TiO2纳米复合材料具有较好的光电性能。 |

| Abstract: | 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. |
