Supported metal catalysts show improved stability and higher activity. Carbon material was chosen as support material which needed high specific surface area and electrical conductivity. In our research, Pt supported with three kinds of different carbon material that has high surface area, hydrophilic property and high conductivity for high efficiency. Electrochemical properties were compared by cyclic voltammetry (CV). Average size and morphology were analyzed by scanning electron microscopy (SEM). Crystallinity, structure and size of catalysts were investigated by X-ray diffraction (XRD). |
