摘要: 通过测定平带电位,澄清了OH-离子在CdSe电极上的吸附情况,发现在S、S2-、OH-溶液中S2-离子优先吸附,结合旋转环盘电极测量,证明n-CdSe电极在多硫溶液界面上的电荷转移过程。

Abstract: From the determination of the flat-band potentials of the n-CdSe anodes in various polysul-fide solutions, the adsorption of OH-ions on the anodes under different conditions and the preferential adsorption of sulfide ions in S-, S2-, OH-electrolytic solutions are clarified. The charge transfer mechanism at the interface of n-CdSe in the pojysulfide solution is elucidated with the help of rotating ring-disk electrode measurements.
