| 摘 要： | 利用原位拉曼光谱和石英晶体微天平(EQCM)技术对高浓度S2O82-在金电极上还原过程中所产生的伴有周期性析氢现象的电势振荡行为进行了研究,进一步证明了S2O82-还原引起的极限扩散耗尽和析氢导致的对流恢复是造成其电势振荡的根本原因.

| Abstract: | In situ Raman spectroscopy and EQCM had been employed to study the potential oscillatory mechanism for the S_2O~2-_8 reduction accompanying periodic hydrogen evolution.These experimental results give further testification of that the electrochemical reactions,i.e.,S_2O~2-_8 reduction and periodic hydrogen evolution,coupled with alternately predominant diffusion and convection mass transfer of S_2O~2-_8,account for the potential oscillations. |
