Improved performance through milling : A method for enhancing the catalytic activity of supported metal nanoparticles is reported. This method enhances the activity for the ethanol electro‐oxidation of a supported palladium catalyst (see picture). The much higher catalytic performance is ascribed to the increased electrochemically active surface area as well as the generation of high‐index facets at the milled nanoparticle surface.
