Carbon material is frequently used as supports to load Platinum (Pt) nanoparticles as catalysts in fuel cell. In our research, Pt supported with two kinds of different carbon material that has high surface area and high conductivity for high efficiency. Graphtie and Multi-walled carbon nanotube is treated by Modified Hummer’s method for making oxygen containing functional group. Combining sonication and reduction method, it is expected to increase high catalyst efficiency by enhanced surface area. Electrochemical properties were compared by cyclic voltammetry (CV) measurements. Average particle size and morphology were analyzed by scanning electron microscopy (SEM). Crystallinity, structure and size of catalysts were investigated by X-ray diffraction (XRD). |
