We observed that platinum nanoparticles films were produced on the surface of a solution containing 1 mmol/L PtCl ions and 0.5-20v% ethanol by irradiating with a few tens keV electron beams (EB). The platinum films, deposited to grassy substrates, showed the fuel-cell catalytic activity. The Pt nanoparticle films prepared using a few tens keV EB induced reduction method were observed to have catalytic activity.
