摘要
采用 Ti Cl4 水解法制备 Ti O2 纳米微粒 ,并研究这种微粒形成的纳米晶薄膜电极的瞬态光电流特性 .利用能带模型和循环伏安特性讨论 Ti O2 纳米晶薄膜电极光生电荷的产生及转移动力学规律 .
TiO 2 nanoparticles were synthesized by the forced hydrolysis of TiCl 4 in an aqueous solution, and the transient photocurrent properties of this TiO 2 nanocrystalline thin film electrode were studied in different electrolytes. The photo induced charge generation and its transport kinetics were discussed according to the energy band model and the cyclic voltammogram of the ITO/TiO 2 electrode.
