In our research, Pt supported with two kinds of different carbon material that has high surface area and high conductivity for high efficiency. Graphite and Multi-walled carbon nanotube are treated by Modified Hummer's method for making site where catalysts grow. During sonication and polyol process, it is expected to increase high catalyst efficiency by enhanced surface area and synergy effect. Electrochemical properties were compared by cyclic voltammetry (CV) measurements. Average particle size and morphology were analyzed by scanning electron microscopy (SEM). The structure of the composites is characterized by Fourier transform infrared spectrometer (FTIR). |
