▎ 摘　　要

Pt nanoparticle (NP)-loaded 1-aminopyrene functionalized reduced graphene oxide composites (Pt/1-AP-rGO) were synthesized by a simple polyol process. The morphology and structure of the resulting composites were characterized by transmission electron microscopy, Raman spectroscopy and X-ray diffraction. In comparison with Pt/rGO, the resulting Pt/1-AP-rGO exhibited much better dispersibility. Higher dispersion and smaller size of Pt NPs was also observed on 1-AP functionalized rGO. As a result, Pt/1-AP-rGO showed higher catalytic activity, better anti-poisoning ability and stability for methanol oxidation. Meanwhile, it also displayed better electrocatalytic performance toward H2O2. The strategy presented here offers an efficient way for the preparation of high-performance electrocatalysts, which will find promising applications in biosensors and fuel cells.
