We have a strong motivation to pursue the possibility of using ion beam technology for the creation of nano-structured catalytic materials and their electrochemical device applications. My talk includes (1) the preparation of noble-metal nanoparticles in a glassy carbon (GC) substrate by the metal-ion implantation method, (2) heavy-ion-induced lattice defects in the GC substrate and their effect on the oxygen reduction reaction activity of the deposited platinum nanoparticles, and (3) the formation of polymer nanostructures and their potential as a catalyst support.
