Effective PdPtMoCrCoNi alloy nanosheets boost electrocatalytic activity and stability for ethylene glycol oxidation

In the realm of traditional electrocatalytic processes, the benefits of composition and two-dimensional ultrathin morphology have not often been explored in the context of multicomponent palladium-based nanosheets. In this work, we utilize a one-step solvothermal method to create nanosheets of a multicomponent alloy (PdPtMoCrCoNi NSs). The synthesis involves no surfactants, allowing for the exposure of more active sites or surface atoms. The resulting PdPtMoCrCoNi NSs exhibits outstanding performance in the electrooxidation of ethylene glycol under alkaline conditions, demonstrating high mass activity (10.12 A mgPd+Pt−1), good stability, and enhanced anti-poisoning ability. The incorporation of more low-cost alloyed elements not only reduces the overall cost of electrocatalysts but also effectively tailors the electronic state to enhance the corresponding electrocatalytic performance.
