Some of the most challenging issues in energy conversion are the insufficient activity of the catalysts for the oxygen-reduction reaction, catalyst degradation and carbon-support corrosion. A class of mesostructured carbon-free metallic catalysts based on thin films and with tunable near-surface composition, morphology and structure that lead to an improved affinity for the electrochemical reduction of oxygen are now reported.
