Herein, we report a method to estimate the thermodynamic potentials of electrochemical reactions at different temperatures. We use a two-term Taylor series approximation of thermodynamic potential as a function of temperature, and we calculate the temperature sensitivity for a family of twenty seven known half reactions. We further analyze pairs of cathode and anode half-cells to pinpoint optimal voltage matches and discuss implications of changes in temperature on overall cell voltages. Using these observations, we look forward to increased interest in temperature and idealized half-reaction pairing as experimental choices for the optimization of electrochemical processes.
在此,我们报告一种估算不同温度下电化学反应热力学势的方法。我们使用热力学势随温度变化的两项泰勒级数近似,并计算了27个已知半反应族的温度敏感性。我们进一步分析了阴极和阳极半电池对,以确定最佳电压匹配,并讨论温度变化对电池总电压的影响。基于这些观察结果,我们期待人们对温度和理想化半反应配对作为优化电化学过程的实验选择产生更大的兴趣。
