Recently, biomass-derived oxygenated hydrocarbons, such as ethanol, propanol and ethylene glycol have been demonstrated as potential fuels in the DMFC-like fuel cells, since such biomass-derived molecules are renewable and CO2 neutral. Ethylene glycol and glycerol, which can be produced from biomass, would be promising because they are less toxic and inflammable, and also possess relatively high theoretical energy density. In this study, we investigate the structural, electronic and electrochemical features of carbon-supported ternary PtRuSn (PtRuSn/C) andgraphene-supported PtRu (PtRu/G)catalystsfor the electrooxidation of ethylene glycol and glycerol. The PtRuSn/C and PtRu/G catalystsare characterized by various physicochemical analyses such as XRD, TEM, EDS, TGA, XPS and XANES.
