摘 要：Syntheses of platinum (Pt) nanoparticles have been intensively studied for their application to polymer electrolyte fuel cells (PEFCs), in which a sluggish oxygen reduction reaction (ORR) on a cathode is one of the biggest issues. In this research, Pt nanoparticles were prepared by ion implantation in glassy carbon (GC) substrates for the first time. We expect that ion implantation and the subsequent thermal treatment can achieve efficient growth of the particles leading to high-performance catalysts with less amount of expensive noble metal. This report describes our preparation procedure and morphological properties of the formed Pt particles.
