| 中文摘要 | in this contribution, we for the first time report the synthesis of raspberry-like hierarchical au/pt nanoparticle (np) assembling hollow spheres (rhahs) with pore structure and complex morphology through one in situ sacrificial template approach without any post-treatment procedure. this method has some clear advantages including simplicity, quickness, high quality, good reproducibility, and no need of a complex post-treatment process (removing templating). furthermore, the present method could be extended to other metal-based np assembling hollow spheres. most importantly, the as-prepared rhahs exhibited excellent electrocatalytic activity for oxygen reduction reaction (orr). for instance, the present rhahs-modified electrode exhibited more positive potential (the half-wave potential at about 0.6 v), higher specific activity, and higher mass activity for orr than that of commercial platinum black (cpb). rotating ring-disk electrode (rrde) voltarnmetry demonstrated that the rhahs-modified electrode could almost catalyze a four-electron reduction of o-2 to h2o in a 0.5 m air-saturated h2so4 solution. |
