In situ determination of the nanostructure effects on the activity, stability and selectivity of Pt-Sn ethanol oxidation catalysts

Nanoparticle catalysts comprising two PtSn alloys with different Pt:Sn atomic ratios and a Sn modified Pt catalyst were prepared in order to study the effect of the particle nanostructures on the activity towards the ethanol electrooxidation and the selectivity to CO2. An accurate model of the elect...
