摘要: Macroscopic free-standing Pd and Pd/Pt bimetallic monolayer nanomembranes (Pd- Pd/Pt-FNMs) derived from the spontaneous self-assembly of as-produced NPs at water-air interface within 15 min are fabricated, respectively. The one-step method allows growth high-quality Pd-based FNMs with well-defined morphology, which exhibit significantly higher electrocatalytic activity for methanol/ethanol oxidation than commercial catalysts.
