PREPARATION OF SUPPORTED Pt FROM INTERCALATION COMPOUNDS

Anode catalysts for methanol oxidation were prepared by subsequent reduction of Pt(IV) chloride graphite intercalation compounds (GICs) and Pt(IV) chloride acetylene black intercalation compounds. The intercalation compounds were obtained by the reaction of H 2PtCl 6 with graphite and acetylene black respectively under an inert atmosphere. Two methods were employed in preparation of carbon supported platinum catalysts from intercalation compounds: one was pyrolysis and another chemical method. The activity of catalytics from pyrolysis is higher than that from chemical reduction.
