Abstract
Single or mixed oxides of iron and nickel have been examined as catalysts in photocatalytic water oxidation using [Ru(bpy)3]2+ as a photosensitizer and S2O8 2- as a sacrificial oxidant. The catalytic activity of nickel ferrite (NiFe2O 4) is comparable to that of a catalyst containing Ir, Ru, or Co in terms of O2 yield and O2 evolution rate under ambient reaction conditions. NiFe2O4 also possesses robustness and ferromagnetic properties, which are beneficial for easy recovery from the solution after reaction. Water oxidation catalysis achieved by a composite of earth-abundant elements will contribute to a new approach to the design of catalysts for artificial photosynthesis. © 2012 American Chemical Society.
