英文摘要	hollow pdpt nanocages were prepared by applying potential cycling treatment on core shell pd@pt nanodendrites in 0.5 m sulfuric acid aqueous solutions, during which pd core was dissolved and the pd@pt structure was transformed to hollow nanocages. the nanocages were comprised of bimetallic pdpt nanoalloys, which was confirmed by high-resolution tem (hrtem), scanning tem-energy dispersive x-ray spectra (stem-edx), x-ray diffraction (xrd) and cyclic voltammetry (cv). the pdpt nanocages presented superior catalytic activity toward oxygen reduction reaction in comparison with pd@pt nanodendrites and commercial pt/c catalysts owing to the alloying effect and special morphology. the nanocage morphology was still maintained after long-term durability testing, indicating good structure stability.
