Abstract

The atomic structure of an electrodeposited Ni catalyst film is dominated by extensive di-μ-oxido bridging between Ni(III/IV) ions, as revealed by X-ray absorption spectroscopy. The structure is surprisingly similar to that of an analogous Co-based film and colloidal Mn-based catalysts. Structural requirements for water oxidation are discussed.
