Pt45RU45M10/C (M = Fe, Co, and Ni) catalysts were synthesized and physical and electrochemical properties were analyzed by XRD, TEM, CO stripping and methanol electro-oxidation activity measurement. Among these catalysts, the Pt45RU45Fe10/C catalyst exhibited the highest mass activity of 2.6 A/g catal. while those of the Pt45RU45Co10/C and Pt45RU45Ni10/C catalysts were 2.2 and 2.5 A/g catal., respectively. In the case of specific activity, the catalysts exhibited much higher activities of 110 (130%), 120 (140%) and 150 (170%) mA/m(2) for the Fe, Co and Ni incorporated catalysts, respectively, than 88 mA/m(2) of a commercial PtRu/C catalyst.
