| 摘 要： | 采用阴极恒电位沉积法,在介孔TiO2薄膜上制备了介孔TiO2/CdS薄膜光电极,用XRD,SEM,Raman,SPS和UV-Vis等多种手段对薄膜电极进行了表征.结果表明,CdS成功沉积到介孔TiO2的表面和孔道内,形成了异质结结构.通过光电流作用谱考察了该复合体薄膜电极的光电性能,结果表明,与单纯的介孔TiO2薄膜相比,其光电转换效率显著提高,这是由于CdS具有吸收可见光的特性以及CdS与介孔TiO2形成异质结从而使得光生载流子更容易分离的结果. |

| Abstract: | Mesoporous TiO2/CdS thin film photoelectrode was successfully prepared by electrodeposition CdS nanoparticles on mesoporous TiO2 thin film. The products were characterized by XRD,SEM,Raman,SPS and UV-Visible spectra. The results revealed that CdS nanoparticles were successfully deposited on the surface and in the hole of mesoporous TiO2 thin film. The photoelectric property of these films were investigated by photocurrent action spectra. The results show that the composite films exhibited enhance photoelect... |
