Platinum is generally regarded as the best (electro)catalyst for the oxygen reduction reaction. The catalysts described here use monolayers of platinum on various nanoparticles to achieve low platinum loading, high precious-metal mass activities, and improved resistance to dissolution of platinum during the reaction.
