The discovery of robust and efficient water oxidation catalysts based on first-row transition metal complexes is still a challenge. Here, we describe the underlying chemistry related to the deactivation pathways of first-row transition metal complexes and put forward a series of principles and basic checks to enable the development of robust catalysts.
Metrics are a useful way to assess biocatalyst performance and, when compared to techno-economic targets, can help set goals for further enzyme and bioprocess research and development. Here, we outline some of the remaining challenges to ensure wider acceptance of this approach, both in industry and in academia.
