Resumo
PtSn/C electrocatalyts are claimed to be active electrocatalysts for ethanol electrooxidation and their performances depends greatly on the preparation procedure and
Pt:Sn atomic ratio. In this work, PtSn/C electrocatalysts with Pt:Sn atomic ratios of 9:1,
3:1, 1:1 and 1:3 were prepared in water/ethylene glycol using electron beam irradiation.
The obtained materials were characterized by EDX and XRD and tested for ethanol
electro-oxidation in acid medium using chronoamperometry. X-ray diffractograms of
PtSn/C electrocatalysts showed typical face-centered cubic (fcc) structure of Pt with
average crystallite size of 2 nm and the presence of a SnO2 phase (cassiterite). PtSn/C
electrocatalysts prepared with Pt:Sn atomic ratios of 9:1 and 3:1 were more active for
ethanol electro-oxidation than commercial PtSn/C BASF electrocatalyst.
