The catalysing activities of Pt/Pt and Pt-Sn/Pt electrodes with different Pt:Sn ratios were investigated with conventional electrochemical technique for ethylene glycol (EG) oxidation.The self-dissociation phenomenon of EG to produce strong adsorption intermediate COad at Pt/Pt and Pt-Sn/Pt electrodes was found for the first time.And with the additive of Sn the self-oxidation dissociation of EG at Pt-Sn/Pt electrodes was suppressed.The adsorption quantity of CO produced by the self oxidation dissociation of EG at Pt-Sn/Pt electrodes decreased with increasing Sn:Pt ratio (from 4:1 to 3:2).The apparent activation energy of EG electro-oxidation also decreased (from 44.21 to 32.11 kJ/mol) with increasing Sn-Pt ratio.Compared with Pt/Pt electrode,the onset oxidation potential and apex oxidation potential of EG oxidation shifted negatively by 195 and 105 mV respectively,and the current inreased from 0.117 1 to 0.148 1 mA.
