摘 要: | 应用电化学循环伏安法,以银作工作电极研究了水合肼在离子液体BmimPF6中的氧化过程.结果显示,银离子对水合肼的氧化过程具有催化作用,其氧化峰电位0.16V(vs.SCE)电催化反应速率决定步骤为1电子的氧化还原过程.在0~3.4mmol/L肼浓度范围内,催化反应峰电流与肼浓度间具有良好的线性关系.

Electrochemical Behaviors of Hydrazine in BmimPF_6 Solution at Ag Electrode |
| |
Abstract: | In this work,the electrochemical behaviors of hydrazine at Ag electrode in the room temperature ionic liquid,BmimPF6,were studied by cyclic voltammetry. Results suggested that Ag electrode showed a good catalytic activity towards hydrazine oxidation. The catalytic peak current showed a good linear relationship with the hydrazine concentration in the range of 0 ~ 3. 4 mmol/L. The rate-determining step of the electrocatalytic reaction involved one electron transfer form hydrazine molecule to Ag + ion. |
