以惰性金属、氧化-还原体系和多孔碳材料作为准参比电极,以二茂铁的氧化-还原半峰电位值为内标,对准参比电极在季铵盐有机电解液中的稳定性进行研究。结果显示,金属准参比电极无法建立稳定的电荷平衡体系,其参比电位稳定性较差;氧化-还原体系可以在一定时间和范围内具有稳定的电荷平衡体系,但长时间工作电荷平衡体系会被破坏,导致参比电位稳定性变差;高比表面积多孔碳材料准参比电极具有大量的双电层电容,因而可以建立稳定的电荷平衡体系,具有良好的参比电位稳定性。
以惰性金屬、氧化-還原體繫和多孔碳材料作為準參比電極,以二茂鐵的氧化-還原半峰電位值為內標,對準參比電極在季銨鹽有機電解液中的穩定性進行研究。結果顯示,金屬準參比電極無法建立穩定的電荷平衡體繫,其參比電位穩定性較差;氧化-還原體繫可以在一定時間和範圍內具有穩定的電荷平衡體繫,但長時間工作電荷平衡體繫會被破壞,導緻參比電位穩定性變差;高比錶麵積多孔碳材料準參比電極具有大量的雙電層電容,因而可以建立穩定的電荷平衡體繫,具有良好的參比電位穩定性。

The stability of quasi-reference electrode based on inert metal, oxidation-reduction system, and porous carbon materials was investigated by using Fc/Fc+ as an internal standard in organic electrolyte. The results show the reference electrode of inert metal is not able to establish a stable charge-balancing process, so its stability of reference potential is poor; the charge-balance of oxidation-reduction system is able to maintain within a short time, however the charge-balance is destroyed for long testing time, which leads to the deterioration of stability of reference potential; activated carbon has a good stability of the reference potential due to its large number of electric double layer which is able to establish an a stable charge balance system.
