Multiple proton-coupled electron transfer and structure sensitivity in electrocatalysis

Marc T.M. Koper

Leiden Institute of Chemistry, Leiden University, PO Box 9502, 2300 RA Leiden, The Netherlands

ABSTRACT

This talk will outline a simple but general theoretical analysis for multiple proton-electron transfer reactions, based on the microscopic theory of proton-coupled electron transfer reactions, recent developments in the thermodynamic theory of multi-step electron transfer reactions, and the experimental realization that many multiple proton-coupled electron transfer reactions feature decoupled proton-electron steps in their mechanism. The theory will be discussed in relation to the experimental results for a number of redox reactions that are of importance for sustainable energy conversion, including hydrogen en oxygen evolution, and the electrocatalytic reduction of CO2, focusing on their pH dependence and structure sensitivity.
