Platinum ring/glassy carbon disk electrodeIt is one of the important tools for electrochemical measurement, and its main structure is to place a concentric ring on the same plane as the disk, with insulation material separating the disk from the ring electrode. Disk electrodes are usually made of the material being studied, while ring electrodes are typically made of platinum or gold. The rotating ring disk electrode is particularly suitable for studying the intermediate products of electrode reactions and is also useful for studying the mechanism of electrode processes. Therefore, it has been widely used in the study of metal corrosion processes, chemical power sources, electroanalytical chemistry, and electroorganic synthesis.
