Earth-Abundant Heterogeneous Water Oxidation Catalysts
TLDR
It is suggested that future advances in solar fuels science will be accelerated by the development of new methods for materials synthesis and characterization, along with in-depth investigations of redox mechanisms at catalytic surfaces.Abstract:
Water oxidation is a key chemical transformation for the conversion of solar energy into chemical fuels Our review focuses on recent work on robust earth-abundant heterogeneous catalysts for the oxygen-evolving reaction (OER) We point out that improvements in the performance of OER catalysts will depend critically on the success of work aimed at understanding reaction barriers based on atomic-level mechanisms We highlight the challenge of obtaining acid-stable OER catalysts, with proposals for elements that could be employed to reach this goal We suggest that future advances in solar fuels science will be accelerated by the development of new methods for materials synthesis and characterization, along with in-depth investigations of redox mechanisms at catalytic surfacesread more
