▎ 摘　　要

Electrochemical analysis of platinum (Pt) supported on single-walled carbon nanotube (SWCNT) and reduced graphene oxide (RGO) composites were investigated. The Pt/SWCNT/RGO composite simultaneously synthesized by chemical reduction method in ethylene glycol (EG) solution. The catalytic activity of Pt/SWCNT/RGO composite compared with that of Pt/RGO composite. The SWCNT in graphene oxide sheets can serve as functioned spacers which impede aggregation of GO. The prepared Pt/SWCNT/RGO composite presented improved performance in terms of electrocatalytic activity. Electrochemical properties of the composite were characterized by cyclic voltammetry (CV). The morphology and structure of the composites indicated that the Pt nanoparticles were deposited on the RGO or SWCNT and the SWCNTs were located between RGO sheets by field emission scanning electron microscopy (FE-SEM) and transmission electron microscope (TEM).
