Electrocatalytic Activity Of Electrochemically Dealloyed PdCu3 Intermetallic Compound Towards Oxygen Reduction Reaction In Acidic Media

A structurally ordered phase of PdCu₃ nanoparticles (NPs)/carbon black (CB), in which PdCu₃ has a Cu₃Au-type structure, was prepared by co-reduction of Pd and Cu precursors using ethylene glycol as a reducing agent and an annealing procedure.
