Abstract: A general protocol for the synthesis of Pt-Sn/C catalysts for ethanol electrooxidation by the polyol method is developed after a systematic variation of the preparation variables. This protocol enables the complete transfer of all catalytic elements in the preparation solution to the catalyst support; thereby providing a convenient means of catalyst composition control. Water is a necessary co-solvent for ethylene glycol in the polyol synthesis of Pt-Sn/C catalysts. The best preparation medium for controlling the particle size to small sizes is 0.1M NaOH solution in a mixture of equal volumes of water and ethylene glycol. With this medium composition Pt-Sn/C catalysts with the optimized target Pt:Sn atomic ratio of 3:1 could be expeditiously prepared for ethanol electrooxidation.
