| 摘 要： | 在体积比１∶１的水－甲醇溶液中，用循环伏安法和旋转石墨电极法研究了被吸附在电极表面的和溶液中的２，３，５，６－四（２－呲啶基）吡嗪（ＴＰＰ）的还原过程，实验发现该配位体的电活性中心吡嗪基团在还原过程中，无论是表面吸附的还是溶解的ＴＰＰ，都是在得到２个电子的同时也得到２个质子，测定了该配位体的表观电位和扩散系数。

| Abstract: | The irreversible adsorption of the ligand of 2,3,5,6-tetrakis(2-pyridyl)pyrazine on pyrogenic graphite eletrodes were exmined by surface cyclic voltammetry.The electrochemical reactions of the two electron and two proton of pyrazine group in the studied molecule were identified.The formal potential and diffusion coefficient of TPP ligand were also determined. |
