Abstract

Co and Ni-substituted structurally ordered intermetallic PdCu₃ nanoparticles (NPs) synthesized at low temperature exhibit remarkable enhancement of the ethanol electrooxidation (EOR) activity with improved durability. The first-principle calculations suggest that prompted generation of OH and CH₃CO radicals in close proximity and shifting of the d-band center towards the Fermi level boost the EOR efficiency.
