一种体系温度可控的光电通用型三电极电解池
本专利技术涉及电化学电解池装置领域，具体涉及一种体系温度可控的光电通用型三电极电解池。
技术介绍
电化学是研究电作用和化学作用交互关系的化学分支，通过施加不同的电位，来观测研究对象的不同电流情况；是基于电解池内电解液的组成与含量，不同的电极材料和电解参数与其电化学性质的关系而建立起来的一类分析方法。根据不同的施加信号，电化学分析法可分为循环伏安法、线性伏安法、交流阻抗法、电位法和电解法等。但无论采用哪一种类型的电化学分析方法，都必须在电解池中进行，因此电解池对各类电分析研究有着不可替代的作用。常见的电解池是两电极体系，其有一个阴极和一个阳极，通过盐桥相连接构成一个完整的系统。此体系结果简单、测试方便，但是由于体系中存在电流的通过，会在体系溶液中产生压降，导致施加的外电压大于体系需要电压，导致测量结果有较大误差；另外，体系中存在的电流也会使对电极产生极化，导致工作电极的电位难以精确测定。为了解决两电极体系中存在电流的问题，在体系中增加了具有稳定电位的参比电极。因为电流不流经参比电极，所以参比电极并不会产生极化现象。通过参比电...
