摘要：
Pt-GO composites with high-number-density Pt nanoparticles dispersed uniformly on GO nanosheets were prepared using ethylene glycol as reducer at 180 degrees C. The nanoparticles had an average size of 12 nm with corners and edges on their surfaces. The composites had electrochemically active surface area of 31.7 m(2) g(-1) with a ratio (I-f/I-r=0.96) of the forward anodic peak current (I-f) to the reverse anodic peak current (I-r) in cyclic voltammetry curves, which is much higher than those of the reported Pt nanodendrites/reduced graphene oxide composites.
