Highly branched ultrathin Pt-Ru nanodendrites (NDs) with an average thickness of similar to 1.8 nm and controlled elemental ratios were prepared through nanoconfined and epitaxial growth inside lamellar micelles of designed surfactants. The elemental compositions could be easily extended to other metals (Pt-M, M = Rh, Co, Fe, Ag, etc.). Owing to their synergistically structural and compositional advantages, Pt-Ru NDs with a specific atomic ratio (specifically Pt90Ru10) showed enhanced electrocatalytic activity and stability toward the methanol oxidation reaction (MOR) under alkaline conditions.
