Using sodium citrate as a stabilizer, sodium borohydride as a reductant, 20%(w) Pt60Ru30Co10/C catalyst was prepared by impregnating reduction. Transmission electron microscopy (TEM) and X-ray diffraction (XRD) were used to characterize the catalysts. We studied the catalytic activity and stability in a methanol solution at different pH values and pre-adsorbed CO monolayer stripping was used to investigate its anti-poisoning ability. The results showed that PtRuCo/C had the highest catalytic activity toward methanol at pH 8, and its catalytic activity and stability were much higher than that of commercial Pt50Ru50/C. Compared with Pt50Ru50/C, the pre-adsorbed CO monolayer oxidation potential showed a significant negative shift.
