In the race for cost-effective electrocatalytic water oxidation, the most promising materials appear to be metal oxides, layered double hydroxides, Prussian-blue-type coordination polymers, and supported polyoxometalates. All exhibit advantages and disadvantages, depending on working conditions, for the development of a technically and economically efficient platform for artificial photosynthesis, as discussed by J. R. Galán-Mascarós in this review.
