Abstract
Ni:Fe:Al mixed oxides were identified as highly active water oxidation electrocatalysts. A systematic investigation of these materials has led to the characterization of a well-defined NiFeAlO4 inverse spinel catalyst. Electrochemical characterization of NiFeAlO4 shows activity exceeding previously reported catalysts of similar composition and/or structure, including NiO, NiFe (9 : 1), and NiFe2O4.Keywords
