Abstract
We describe herein a method for the simultaneous measurement of temperature and electrochemical signal with a new type of thermocouple microelectrode. The thermocouple microelectrode can be used not only as a thermometer but also as a scanning electrochemical microscope (SECM) tip in the reaction between tip-generated bromine and a heated Cu sample. The influence of temperature on the SECM imaging process and the related kinetic parameters have been studied, such as kinetic constant and activation energy.
摘要
我们在此描述了一种利用新型热电偶微电极同时测量温度和电化学信号的方法。这种热电偶微电极不仅可以用作温度计，还可以在尖端生成的溴与加热的 Cu 样品之间的反应中用作扫描电化学显微镜 (SECM) 的尖端。我们研究了温度对 SECM 成像过程和相关动力学参数（如动力学常数和活化能）的影响。
