Platinum modified with cerium oxide (Pt-CeO) is considered as promising cathode materials for use in polymer membrane electrolyte fuel cells. A key process to make this active is formation of highly dispersed Pt nanoparticles on a CeO surface. Therefore, there is a strong motivation for us to use this radiation technique for precipitation of the Pt nanoparticles on CeO films, which would be expected to be a model electrocatalyst of Pt-CeO. We deposited the CeO films on a SiO substrate by magnetron sputtering. The CeO films in an aqueous solution containing HPtCl and CHOH were irradiated with 2 MeV electron beams and Co -rays at 50 kGy at maximum. The detailed analysis revealed homogeneous precipitation of metallic Pt by the irradiation with both the radiations, suggesting high applicability of the radiation-induced precipitation method to the preparation of the model Pt-CeO electrocatalysts.
