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