Abstract

This article presents an overview of the established basis needed for the oxidation of water to dioxygen, and thus the demands a catalyst needs to fulfill to be able to perform this reaction. It further describes the structure, redox properties, and performance of selected molecular catalysts that have been reported to be able to perform this difficult reaction and that can be considered as references in the field. The scarce reaction mechanism studies that have been described are also summarized and discussed. The article mainly deals with Ru complexes, because they constitute most of the available literature at the moment, and are classified as a function of their nuclearity. Other transition metal complexes of relevance based on Ir, Co, and Mn are also described. Finally, a few conclusions are drawn from the global description of all of the catalysts presented here, and the challenges and opportunities in the field are also discussed.
