Abstract质子交换膜燃料电池(PEMFC)催化电极材料的制备方法是当今能源科学研究的热点之一。其中,嵌段共聚物自组装技术因操作简单和结构可控而倍受关注。本文以PS-b-P4VP嵌段共聚物自组装形成的有机纳米膜结构为模版,探讨了铂(Pt)纳米阵列的制备,并测试了其催化效率。结果表明,本方法制备的Pt阵列均匀有序,电化学活性面积为131.97 m^2/g,而Pt消耗仅为商业化标准的6%左右,从而在保持催化活性的同时,提高了Pt的利用率和催化效率。
Other AbstractRecently, researches have been increasingly devoted to the nanomaterials of proton exchange membrane fuel cell (PEMFC) electrocatalysts for their unique nanoscale surface effects. As one of the most important methodologies of material preparations, self-assembly of block copolymers (BCs) stands out with its inherent ability to form complex nanostructures. Herein, a simple but robust fabrication of Pt nanoparticles (NPs) assisted by self-assembly of PS-b-P4VP BC template on silicon wafers was introduced. The as-prepared Pt electrocatalyst showed high order and high EASA value of 131.97m^2/g with a low loading of about 6wt% of the standard commercial PEMFC Pt-cost. This work supplied a precise control for the increase of catalytic ability and Pt utilization.
