| 摘 要： | 利用电化学氧化还原法获得了具有SERS活性的粗糙锌电极，现场检测了其在不同浓度氢氧化钾溶液中随电位变化的表面拉曼光谱。锌氧化物拉曼信号在不同浓度氢氧化钾溶液中存在着很大的差异，说明氢氧根离子浓度对锌的氧化过程有很大的影响。根据所得拉曼谱图，作者尝试着给出不同浓度氢氧化钾溶液中锌的成膜过程及机理。

| Abstract: | Electrochemical oxidation-reduction method was employed to roughen Zn electrode for obtaining SERS, and potential dependent surface enhanced Raman spectra (SERS) of roughened Zn electrode in KOH solution of different concentration wereobserved. The spectra of Zn electrode in various solutions had obvious differences which indicated the concentration of OH~- had a great effect on the dissolution and passivation of zinc. Based on our experimental results, the authors attempt to analyse the behavior of zinc in alkaline and give the mechanism of its passivation. |
