Developing of novel catalysts, able to substitute Pt in low temperature fuel cell anodes due to its high price and low CO-tolerance is industrially vital. Alloying Pt with cheaper transition metals such as nickel, cobalt, iron, etc. allows reducing the amount of noble metal and lowering the overall costs of catalysts. Herein, a microwave-assisted method was used to prepare the graphene supported PtCoM (M = Mn, Ru, Mo) catalysts with the different Pt:Co:M molar ratios with the aim to use them as electrocatalysts for the electro-oxidation of methanol and ethanol in an alkaline medium. The prepared PtCoM/graphene catalysts were characterized using Transmission Electron Microscopy and Inductively Coupled Plasma Optical Emission Spectroscopy. The electrocatalytic activity of the graphene supported PtCoM catalysts towards the electro-oxidation of methanol and ethanol in an alkaline medium was investigated using cyclic voltammetry and chrono-techniques.<br/>The data on the electro-oxidation of methanol and ethanol on the PtCoM/graphene catalysts under various conditions are compared and discussed on the basis of electrochemical data.
