제목 Preparation and electrochemical analysis of Pt/SWCNT/rGO composites for improved electrocatalytic activity of Fuel Cells
초록   In this study, the electrochemical analysis of Platinum (Pt) and single-walled carbon nanotube (SWCNT) supported on reduced graphene oxide (rGO) was investigated. Graphene oxide (GO) was prepared from graphite using modified hummer`s method and the Pt/SWCNT/rGO composite was simultaneously synthesized with GO, SWCNT and Pt by chemical reduction method in ethylene glycol (EG). In order to prevent GO from aggregation, the SWCNT existed as functioned spacers between graphene oxide sheets. The result of Pt/SWCNT/rGO indicated that it improved catalytic activity. Electrochemical properties of the composite were characterized by cyclic voltammetry (CV). The morphology and structure of the composite was examined by field emission scanning electron microscopy (FE-SEM), transmission electron microscope (TEM). The functional groups of the composite were further confirmed by fourier transform spectral analysis (FT-IR).
