Fuel cells have promising candidates for use as a power source in portable electric devices and electric vehicles because they have grate potential for high eifficiency, zero-emission power generation. Platinum catalyst have been used as cathode and anode electrode in fuel cells. However, issues such as poor methanol oxidation kinetics, high-cost remain a challenge. Pt-supported on carbonized NH2-MIL-101 and multi-walled carbon nanotubes composites was prepared by pyrolysis process and chemical reduction. The electrochemical characterization and morphological analysis of composites was measured by cyclic voltammetry, chronoamperometry, transmission electron microscope. These results indicate that the Pt-CNT@cNH2-MIL-101 nanocomposite showed electrochemically superior properties to methanol oxidation reaction and the higher electrochemical surface area. Also, carbonized NH2-MIL-101 and modified the CNTs was thought to enhance the effective area of the platinum deposition site. |
