摘要：

The exploration of simple and green synthetic methods and realization of facile composition tuning of nano-materials are key to achieve high catalytic activity. Herein, we successfully achieve a one-pot synthesis of composition-tunable PtCu bimetallic nanodendrites in aqueous solution by an ultrasound-assisted approach, in which ultrasound plays an important role in the nanoparticle growth. After complete removal of surface ligand, these PtCu nanodendrites show very high catalytic activity and stability for methanol oxidation reaction.
