摘　　要：首先采用阳极氧化法制备TiO_2纳米管阵列,结合不同的电化学方法制备具有三维异质结构的CdSe/TiO_2纳米管阵列复合薄膜。结果表明:电解液中加入酒石酸钾钠,采用循环伏安法和恒压沉积法都得到了分散性好,尺寸小而均匀分布的CdSe纳米颗粒。特别是采用循环伏安法制备CdSe/TiO_2纳米管阵列薄膜时,得到直径为15～20nm的立方相CdSe颗粒,且均匀地分布在TiO_2纳米管管内和管口,能够充分地利用TiO_2纳米管阵列的三维结构,形成具有三维异质结构的CdSe/TiO_2纳米管阵列复合薄膜。光电性能结果表明测试,这种具有三维异质结构的CdSe/TiO_2纳米管阵列复合薄膜能够充分利用太阳光,并有效地促进光生载流子的分离和传输,呈现出最佳的光电化学性能。Titanium dioxide(TiO2)nanotube arrays were prepared by anodic oxidation,CdSe/TiO2 nanotube arrays composite films with three-dimensional heterogeneous structures were prepared by different electrochemical methods.The results show when sodium potassium tartartrate was added into the electrolyte,CdSe nanoparticles with good dispersion,small size and uniform distribution are obtained both by cyclic voltammetry and potentiostatic deposition.Especially,the cubic phase CdSe particles with a diameter of 15 to 20 nm are obtained by using cyclic voltammetry,which are distributed uniformly on the inner and pipe mouth of TiO2 nanotubes,so as to make full use of the three-dimensional structure of TiO2 nanotube arrays,and obtain CdSe/TiO2 nanotube arrays composite films with three-dimnsional heterogeneous structures.Through photoelectric chemical testing,the results show that CdSe/TiO2 nanotube arrays composite films with three-dimensional heterogeneous structures can make full use of solar energy,effectively promote the separation and transmission of photon-generated carriers,and present the best photochemical properties.
