pH dependence of OER activity of oxides: Current and future perspectives

- We show the advantage of the RHE reference in pH partial reaction order studies.
- We discuss possible pH-dependent reaction steps for the oxygen evolution reaction.
- A method to convert reaction orders from SHE to RHE reference is provided.
- The reaction order with respect to RHE is measured for RuO2.
- Dependencies of RHE reaction order on material properties are analyzed.
