Rate Law for Photoelectrochemical Water Splitting Over CuO
P型半导体光催化分解水是一种非常有前景的制氢方法.尽管对其反应动力学进行了很多研究并取得了不少进展,但建立其速率方程鲜见文献报道.本文采用积分电量和电化学阻抗谱等多种电化学方法研究了典型p型半导体氧化铜(CuO)光电化学分解水时光生电荷浓度、界面电荷转移速率常数及其与反应速率(光电流表示)之间的关系,力图建立其速率方程.结果表明,电极界面电荷转移速率常数与光生电荷浓度指数相关,光电流等于此速率常数乘以光生电荷浓度,反应级数(以光生电荷计)为一级,…查看全部>>
Photocatalytic splitting of water over p-type semiconductors is a promising strategy for production of hydrogen.However,the determination of rate law is rarely reported.To this purpose,copper oxide(CuO)is selected as a model photocathode in this study,and the photogenerated surface charge density,interfacial charge transfer rate constant and their relation to the water reduction rate(in terms of photocurrent)were investigated by a combination of(photo)electr…查看全部>>
