Abstract
Water is the renewable, bulk chemical that nature uses to enable carbohydrate production from carbon dioxide. The dream goal of energy research is to transpose this incredibly efficient process and make an artificial device whereby the catalytic splitting of water is finalized to give a continuous production of oxygen and hydrogen. Success in this task would guarantee the generation of hydrogen as a carbon-free fuel to satisfy our energy demands at no environmental cost. Hereud we show that very efficient and stable nanostructured, oxygen-evolving anodes are obtained by the assembly of anud oxygen-evolving polyoxometalate cluster (a totally inorganic ruthenium catalyst) with a conducting bed of multiwalledud carbon nanotubes. Our bioinspired electrode addresses the one major challenge of artificial photosynthesis, namelyud efficient water oxidation, which brings us closer to being able to power the planet with carbon-free fuelsKeywords
