Abstract
⺠We added triethanolamine (TEA) into the Pd2+ and Cu2+ mixed-ion electroplating bath to obtain a Pd-rich PdCu alloy. ⺠XRD analysis verified that PdCu alloys have smaller particle sizes compared with those deposited in TEA-free solutions. ⺠The cyclic voltammetry showed that alloys deposited with TEA have higher hydrogen desorption areas. ⺠Surface-modified PdCu alloys via redox replacement displayed the beneficial of Cu underpotential deposition. ⺠PdCu alloys fabricated with TEA and redox replacement showed better catalytic performance in the methanol electro-oxidation.
