In this study, we present the enhanced Pt/SWCNT/RGO composite electrode by inserting SWCNTs between RGO sheets for a methanol oxidation. The Pt/RGO composite were compared with Pt/SWCNT/RGO with various weight ratios of SWCNTs. The SWCNTs act as functioned spacers which inhibit aggregation of RGO sheets as well as smooth migration of ion by making ideal spacer. The enhanced Pt/SWCNT/RGO composite electrode was demonstrated by cyclic voltammetry (CV), chronoamperometry (CA), field emission scanning electron microscopy (FE-SEM), transmission electron microscope (TEM) and fourier transform infrared spectroscopy (FT-IR). |
