Carbon wool ball carried type catalyst and its preparation method and uses

The present invention relates to a catalyst and its preparation method and use of a carbon-supported pompons. The catalyst is a carbon supported pompons 1 ~ 80wt% loading of Pt or PtM alloys supported on carbon Pompon material; said M is Ru, Sn, or Mo. The carbon supported catalyst flocculus prepared by liquid-phase method. The new carbon material, Pompon PtM alloy catalyst supported Pt or for direct alcohol fuel cells. The electrochemical tests show that 1.6 to 3 times the activity of the catalytic electrochemical oxidation of methanol the catalytic activity of this new carbon material Pompon or PtM alloy catalyst supported Pt loading U.S. same kind of catalyst; The new carbon pompons PtSn alloy material loading on the catalytic activity of the electrochemical oxidation of ethanol 2-3 times the catalytic activity of the catalyst of U.S. same kind of loading. Further, the process of the present invention is simple, reproducible, high product purity prepared, stable performance, suitable for industrial mass production.
