摘要
应用涂膜法、电沉积法和溶胶．凝胶法制备纳米TiO2电极．实验发现，纳米TiO2具有特殊的光电化学响应，其光电流，电位变化出现光电流峰，这一特殊的光电化学性质乃与纳米半导体电极的纳米结构及其特殊的光诱导氧化还原反应机理密切相关．
The nano-crystalline TiO2 electrodes were prepared by spread method, electrocleposition and sol-gel method. The experimental results show that the nano-erystaUine TiO2 electrodes have special photoeleetroehemical response-the photocrrent-potential curves appear peaks. The special photoelectrochemical behaviors of nanocrystalline TiO2 electrodes are ascribed to nano-structure as well as special light induced redox reaction mechanism of nano-crystaUine semiconductor electrodes.
