An exploration of the use of Au submonolayer decorated Pd7Ir nanoparticles as a highly active electrocatalyst for the ethanol oxidation reaction in alkaline media

Abstract

Although very promising in its stabilizing effect, an inevitable loss on activity mostly exists when combining gold (Au) with other noble metals. Contrary to this knowledge, in this research an unexpected promotion of the Au submonolayer on palladium-iridium/carbon (Pd₇Ir/C) nanoparticles towards the ethanol oxidation reaction in alkaline media was explored and the corresponding mechanism was clarified.
