One-pot Synthesis of PdCuAg and CeO2 Nanowires Hybrid with Abundant Heterojunction Interface for Ethylene Glycol Electrooxidation

Graphical The hybrid of PdCuAg and CeO 2 nanowires with structural (abundant heterojunction/interfaces and ultrathin nanowire structure) and compositional advantages were facile prepared by one-pot method, thus embracing enhanced electrocatalytic performance for ethylene glycol oxidation reaction. Introducing CeO 2 into Pd-based nanocatalysts for electrocatalytic reactions is a good way to solve the intermediate toxicity problem and improve the catalytic performance. Here we reported a simple strategy to synthesize the PdCuAg and CeO 2 nanowires hybrid via a one-pot synthesis process under strong nanoconfined effect of specific surfactant as templates. Owing to the structural (ultrathin nanowires, abundant heterojunction/interfaces between metal and metal oxide) and compositional (Pd, Cu, Ag, CeO 2 ) advantages, the hybrid showed significantly enhanced catalytic activity (6.06 A mg Pd −1 ) and stability, accelerated reaction rate, and reduced activation energy toward electrocatalytic ethylene glycol oxidation reaction.
