CO2 reduction electrochemistry presents an approach to using renewable electricity for the valorization of abundant or waste feedstocks of CO2 into critical chemicals and fuels via direct, low-temperature processes. This symposium will provide a platform for discussion of research on electrochemical and photoelectrochemical CO2 reduction into fuels. The underlying reactions present many challenges, including scaling relationships in adsorption energies preventing catalyst optimization, branching mechanisms leading to product distribution, challenges in managing multiple phases of reagents and products, and development of reactors for conversion at high rates and yields. This symposium will feature recent progress in addressing these challenges by approaches spanning catalyst design, operando methods development, and device engineering.

Ifan is a Professor in Electrochemistry at the Department of Materials at Imperial College: he leads the Interfacial Electrochemistry Group there and is also Atoms to Devices Research Area Lead at the Henry Royce Institute.
Ifan joined Imperial College in July 2017. Prior to Imperial, he was at the Department of Physics at the Technical University of Denmark (DTU); he was first employed as a postdoctoral researcher, then as assistant professor and finally as associate professor and leader of the Electrocatalysis Group there. In 2015, Massachusetts Institute of Technology (MIT) appointed Ifan as the Peabody Visiting Associate Professor. He taught and conducted research at the Department of Mechanical Engineering at MIT for a whole semester.
Ifan’s research aims to enable the large-scale electrochemical conversion of renewable energy to fuels and valuable chemicals and vice versa. Such processes will be critical in order to allow the increased uptake of renewable energy. His focus is on the catalyst at the electrode, i.e. the electrocatalyst. It turns out that the electrocatalyst material defines the efficiency of several important electrochemical processes, including:(i) electrolysis for the storage of renewable electricity — which is inherently intermittent — in the form of fuels, such as hydrogen or alcohols.(ii) fuel cells as a potentially zero emission source of power for automotive vehicles. (iii) the green synthesis of valuable chemicals, such as ammonia and H2O2. (iv) batteries, which tend to degrade by gas evolution at the electrode-electrolyte interface. Hence the reactions that need to be accelerated in electrolysers and fuel cells — such as CO2, CO, O2 and H2 evolution — are precisely those that need to be inhibited in batteries.
Ifan has discovered or co-discovered several new catalysts for the oxygen reduction reaction, which exhibited significant improvements in performance over the prior state-of-the-art. In particular, his research on hydrogen peroxide production led to the establishment of the spinout company, HP Now.
Ifan is the recipient of RSC's Geoffrey Barker Medal (2024), the RSC's John Jeyes Award (2021). He also currently holds an European Resarch Council Consolidator Grant (2021-2025). Since 2022, he has been a Clarivate Highly Cited Researcher.
