Direct methanol fuel cells (DMFCs) possess many advantages such as compatibility with the existing petroleum distribution network due to the consumption of liquid fuel, and feasibility to handle water and heat management. However, the DMFC anode is limited by poor electrochemical activity for methanol oxidation. Thus, a large amount of Pt-based electrocatalysts must be used and is considerably important for high power density in DMFCs. In this study, core-shell nanostructured carbon materials with pristine carbon black (CB) particle as a core and poly(3,4-ethylenedioxy thiophene) (PEDOT) as a shell were synthesized using emulsion polymerization. CB/PEDOT core-shell nanostructure was confirmed by transmission electron microscopy (TEM), X-ray diffraction (XRD), thermogravimetric analysis (TGA) and fourier transform-infrared spectroscopy (FT-IR). Also, electrical properties of all samples were measured. |
