Abstract
A high active Pt/C(b) catalyst was prepared by chemical reduction. The experimental results showed that the Pt/C(b) catalyst formed by reduction of hexachloroplatinic acid with formic acid has excellent catalytic properties for methanol and adsorbed CO(COad) electro-oxidation. The electrocatalytic activity of the catalyst was characterized as having a specific surface activity of 33.38Â mAÂ cmâ2 at 0.6Â V (versus Ag-AgCl). The Pt in the catalyst was well dispersed on carbon with an electrochemically-active specific surface area (ESA) of 84.16Â m2Â gâ1 and a BET specific surface area of 192.34Â m2Â gâ1 and an average particle size of about 2.6Â nm. The catalyst showed a very good stability for 12Â h.
