Abstract

Recently, 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 131.97 m2/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.

Key words： block copolymer; elf-assembly; Platinum nanoparticles; fuel cell
