Optimized catalysts for direct ethanol fuel cell

Ethanol electrooxidation catalyst PtSn (3:1, 40% Pt) on pyrolytic double-walled carbon nanotubes as a carrier was synthesized by means of modified polyol method. Electrocatalytic activity of the synthesized catalyst in model conditions (0.5М H2SO4 + 1М С2Н5ОН) is higher than that for analogous catalyst on XC 72 carbon and equals to 70 mA/mgcat (E = 0.4 V).
