Water Oxidation: An Efficient CeO₂/CoSe₂ Nanobelt Composite for Electrochemical Water Oxidation (Small 2/2015)

A new CeO2/CoSe2 nanobelt composite is developed as a highly effective water oxidation electrocatalyst by growing CeO2 nanoparticles in situ on CoSe2 nanobelts, via a simple polyol reduction route. As demonstrated by S.-H. Yu and co-workers on page 182, such CeO2/CoSe2 nanobelt composites are able to catalyse exteremely high oxygen evolution reaction (OER) activity, even better than the state-of-the-art RuO2 catalyst in an alkaline medium.
