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.
Highlights
ObjectivesThe aim of our work was to develop a method for the simultaneous acquisition of temperature and electrochemical signals that might be used
Integration of the thermocouple microelectrode with scanning electrochemical microscope (SECM) can satisfy the requirements to measure the local temperature around the tip during SECM measurements
The temperature of the surface of the electrode was calibrated according to a previous report[18]
