Carbon-supported PtRu nanoparticles were prepared by different methods that involve the simultaneous chemical reduction of H 2PtCl 6 and RuCl 3 by NaBH 4 at room temperature ( PtRu-1), by ethanol under reflux ( PtRu-2), and by the thermal decomposition of a single-source molecular precursor [(bipy)...
