The crystallite sizes of these catalysts were determined by X-ray diffraction technique. The specific surface areas of these catalysts were also defined by Brunauer-Emmett-Teller technique. Cyclic voltammetry, chronoamperometry, and electrochemical impedance spectroscopy measurements were conducted on these carbon supported Pt-Ru catalysts to investigate the effect of ruthenium on the ethanol electrooxidation kinetics. Results indicated that Pt-Ru (25:1) catalyst showed the best ethanol electrooxidation activity. In conclusion, ethanol electrooxidation mechanism was proposed.en10.1080/15567036.2013.809391info:eu-repo/semantics/closedAccessAnode catalystelectrochemical impedance spectroscopyelectrooxidationethanolfuel cellsplatinumrutheniumArticle385628634Q2WOS:000374230900003Q4
