摘要：
A series of Pt-Ir-SnO2/C catalysts were synthesized by a modified Bonnemann method. An electrochemical study showed that the Pt-Ir-0.07-SnO2/C catalyst had a three times higher ethanol oxidation current and a two times higher CO2 formation selectivity compared with the Pt/C catalyst under an application voltage of 0.5 V vs the RHE at 25 degrees C. This demonstrates that the Pt-Ir-0.07-SnO2/C catalyst is a potentially ideal ethanol oxidation catalyst for direct ethanol fuel cells.
