Description

technical field [0001] The present invention relates to the technical field of electroanalytical chemistry, and more specifically, relates to an on-site electrochemical microspectral imaging method and system. Background technique [0002] The combination of electrochemistry and spectroscopy gave birth to spectroelectrochemical technology. It is a combined technology that uses electrochemistry as the excitation signal in an electrochemical cell and monitors the response of the electrical excitation signal with spectral technology. [0003] Most of the existing spectroelectrochemical techniques are transmissive, and the main implementation method is: the grid electrode (transparent electrode) is placed in the electrolyte of the electrochemical interface device as the working electrode, and the incident electrochemical reaction occurs at the same time as the working electrode. The light passes through the transparent electrode vertically or parallelly passes through the upper...

AI Technical Summary

Problems solved by technology

[0004] However, when implementing the present invention, the inventor found that the grid electrode (transparent electrode) adopted by the above-mentioned spectroelectrochemical technology has not been industrialized and sold, and the designer needs to make it himself.

However, the commercially available common working electrodes cannot be used in spectroelectrochemical techniques because they are non-transparent electrodes.

[0005] At the same time, the transmitted light collected by the spectrometer hardly contains information on the surface of the working electrode, so it is difficult to collect information on the surface of the working electrode by relying on existing equipment, let alone the imaging information on the surface of the working electrode
