Coming to the surface : The surface composition of carbon‐supported Pt 3 Co catalyst particles changes upon a CO‐annealing treatment. Platinum atoms segregate to the particle surface so that nanoparticles with a platinum shell surrounding an alloy core are formed. This modified catalyst has a superior activity in the oxygen reduction reaction compared to both a plain platinum catalyst and the untreated alloy particles.
