This patent describes a high surface area platinum catalyst which has been prepared by the electrochemical processing of uranium platinum carbide. This Raney-type catalyst has a roughness factor exceeding 3000. The methanol oxidation current at this catalyst was about 1.8 A/cm{sup 2} at 60{degrees}C and a polarization of 1.2 V. Due to the high activity of the catalyst, the inhibition of methanol oxidation at more positive potentials and the consequent hysteresis in the oxidation response were not observed. The preparation, characterization, and evaluation of this catalyst material are also described.
