摘　　要：为了研究氧化还原过程中银电极的组成和结构的变化,将银粉制成粉末微电极.通过对银粉末微电极的循环伏安测试和电化学阻抗谱分析,得知反应过程中的银电极分为内、外两层.在不同的反应阶段,确定了内、外两层的组成和结构.The Ag powder microelectrode was made to survey the changes of its ingredients and structures during the redox process .The cyclic voltammetry and electrochemical impedance spectroscopy study on silver powders mi -croelectrode were carried out and discovered that silver electrode can be divided into two layers , the external and the internal.In addition, the ingredients and structures of two layers were changed at different stages of reaction .

关 键 词：银粉末微电极 氧化还原
