Support service : Pt nanoparticles are deposited on a carbon‐coated titania (CCT) composite (see scheme; MW: microwave) and the activity of the catalyst in the electrochemical oxidation of methanol and reduction of oxygen is examined. The carbon shell stabilizes and disperses the Pt on the TiO 2 . Pt/CCT exhibits a higher electrocatalytic activity than a commercial electrocatalyst, and could be used in direct methanol fuel cells.
