摘　　要：ＣＯ_２在ＴｉＯ_２薄膜修饰ｐ／ｐ~＋－Ｓｉ电极上的光电化学还原魏培海，祁学永淳于宝珠（山东教育学院化学系济南２５００１３）（山东大学化学系济南）关键词二氧化碳，ＴｉＯ_２薄膜，光电化学，ｐ／Ｐ~＋－Ｓｉ电极在半导体电极表面实现ＣＯ２的光电化学还原，可获?..Based on metal organic chemical deposition technique,a thin film of titanium dioxide was grown on the surface of p/p+-Si substrate from tetrabutyl titanate.The structure and transmission spectrum of the film were analyzed by X-ray diffraction and ultraviolet-visible spectroscopy.The photoresponse of p/p+-Si/TiO2 and photoelectrochemical reduction of carbon dioxide on it were studied.In this electrode reaction,formic acid and formaldehyde were obtained and light energy was partially converted into electrochemical energy.
