Abstract

Molecular hydrogen is a promising candidate for replacing fossil fuels. The production of this gas by water splitting requires catalysts to speed up the respective semi-reactions: oxidation of water to O2 and reduction of protons to H2. The development of these catalysts helps to provide a better understanding of the catalytic pathways, allowing the rational design of new active species. In this study the immobilization of a highly active water oxidation molecular catalyst is achieved, reaching over 1 million TONs under catalytic conditions.

Keywords: Water oxidation, catalyst immobilization, ruthenium, water splitting.
