What is the best way to find out active sites of iron oxide electrocatalysts?

25 March 2025 1 10K Report

I am working with iron oxide and oxyhydroxide nanoparticles, and testing them for electrocatalytic OER. I would like to know about the best ways to find out the active sites for calculating TOF. I have tried redox peak integration method, but was not getting the peak.

You must perform the bulk electrolysis and quantify the Faradaic yield. Then, the apparent TOF is the ratio of O2 formation in mole/s and the total amount of Fe in moles in your catalyst. The confirmation O2 evolution is obligatory.
