Studies on Temperature Effects of Bianthrone Reduction Via Electrochemical Homogeneous Redox Catalysis

本文以双蒽酮-醌类为体系研究电化学均相催化反应的温度效应,该体系在15-55℃之间的循环伏安行为显示催化效率随温度增加,其主要原因是均相反应的速度随温度增加,利用数字模拟工作曲线,测定了该体系的某些动力学参数随温度的变化.通过数据分析,指出了该体系中各反应的特征.

The temperature effects on the electrochemical homogeneous redox catalysis have been studied in bianthrone-quinone systems. The temperature range taken in the experiments was 15—55℃ The catalytical efficiency is found to be increased with temperature,which is caused by the increase of the homogeneous reaction rate with temperature. Variations of some kinetical parameters of the system with temperature are determined by working curves obtained from the digital simulation. Based on the data analysis, the characteristics of each reaction in the system are pointed out.
