| Summary: | Bimetallic catalysts PtRh@Pt 5/C with different deposit structures were prepared by force deposition followed calcination at 400°C and characterized by cyclic voltammetry (CV) combined with XRD. The activity of the obtained catalysts was examined in methanol electrooxidation by CV. It was found that PtRh@Pt 5/C catalysts achieved higher catalytic activity and better tolerance to CO compared with Pt 5/C. The surfaces of PtRh@Pt 5/C derived from sandwich-like deposit structure was composed of crystallites and amorphous of PtRh alloys, showing exceptional catalytic activity in methanol oxidation with peak potential shifting 0.03V negatively and 90% increase in current density. © (2011) Trans Tech Publications. |
