Partial　substitution　of　Cu　by　Pd2+　ions　and　Bi3+　ion　self-adsorption　processes　are　used　to　fabricate　a　novel　core-shell　PdCuBi　nanocatalyst.　X-ray　diffraction,　transmission　electron　microscope,　energy-dispersive　X-ray　spectra　and　different　electrochemical　measurements　are　used　to　characterize　the　catalyst.　It　is　exhibited　that　Pd　covers　Cu　outer　layers　in　the　substitution　reaction　and　Bi　modifies　Pd　surface　in　the　adsorption　process.　The　peak　current　for　ethylene　glycol　electrooxidation　of　PdCuBi/C　(171.1　mA　cm(-2))　in　a　KOH　solution　is　almost　three　times　higher　than　that　of　Pd/C　(57.8　mA　cm-2).　Durability　and　tolerance　towards　strongly　adsorbed　intermediate　poisoning　of　this　catalyst　are　also　improved.　(C)　2013　Elsevier　B.V.　All　rights　reserved.
