在溶液中加入钴(Ⅱ)离子能够催化n-TiO_2电极上的光电化学析氧反应,增加光电流-电压曲线的充满因子.用钴修饰的n-TiO_2电极能提高光电流,并催化溶液中铈(Ⅲ)的光氧化反应.本文对这两种催化反应的机理进行了讨论.
The addition of cobalt (Ⅱ) ions to the solution can catalyze the photoelectrochemical oxygen evolution reaction at the n-TiO_2 electrode and increase the photocurrent-voltage curve fullness factor. The cobalt-modified n-TiO_2 electrode can increase photocurrent and catalyze Photooxidation of cerium (Ⅲ). The mechanism of these two catalysis reactions is discussed in this paper.
