Back Cover: A Tailor-Made Molecular Ruthenium Catalyst for the Oxidation of Water and Its Deactivation through Poisoning by Carbon Monoxide (Angew. Chem. Int. Ed. 15/2013)
Two single-site ruthenium catalysts display a Janus-face-type behavior despite structural similarities. One complex is an efficient catalyst for the oxidation of water whereas the CO-containing complex, formed during catalysis, was found to be inactive. In their Communication on page 4189 ff., B. Åkermark and co-workers present a previously undiscovered deactivation pathway for ruthenium-based water-oxidation catalysts. Extensive studies were carried out to explain the diverse behavior in catalysis.
