Pt-Ir-SnO sub(2)/C Electrocatalysts for Ethanol Oxidation in Acidic Media

A series of Pt-Ir-SnO sub(2)/C catalysts were synthesized by a modified Boennemann method. An electrochemical study showed that the Pt-Ir sub(0.07)-SnO sub(2)/C catalyst had a three times higher ethanol oxidation current and a two times higher CO sub(2) formation selectivity compared with the Pt/C c...

Summary:A series of Pt-Ir-SnO sub(2)/C catalysts were synthesized by a modified Boennemann method. An electrochemical study showed that the Pt-Ir sub(0.07)-SnO sub(2)/C catalyst had a three times higher ethanol oxidation current and a two times higher CO sub(2) formation selectivity compared with the Pt/C catalyst under an application voltage of 0.5 V vs the RHE at 25 degree C. This demonstrates that the Pt-Ir sub(0.07)-SnO sub(2)/C catalyst is a potentially ideal ethanol oxidation catalyst for direct ethanol fuel cells.
