The　electrocatalyst　PtBi　with　a　Pt　solid-solution　phase　has　been　synthesized　using　sodium　hypophosphite　as　a　reducing　agent.　The　results　of　X-ray　diffraction　and　X-ray　absorption　near-edge　spectroscopy　showed　that　in　the　presence　of　P,　the　Pt-Bi　system　forms　an　alloy　with　a　Pt　face-centered　cubic　solid-solution　phase　structure.　Electrochemical　test　results　revealed　that　PtBi/XC-72　exhibited　a　good　electrocatalytic　activity　in　the　oxidation　of　methanol.
