How to relate redox peak intensity and catalytic performance of metal electrodes?

31 March 2022 0 395 Report

Hi Everyone,

I am working on metal electrodes for OER in alkaline electrolytes. Three electrodes are prepared by depositing the same catalyst over NiF at different deposition times from 60 to 180 minutes and OER activity is investigated, LSV curves are attached. The best performance is shown by the electrode (2-h) however, its pre-oxidation peak intensity is comparatively not stronger than other samples (1-h and 3-h). How do relate OER activity with peak intensity?

Thanks in advance

Best Regards,
