Direct methanol fuel cells (DMFCs) are considered promising candidates for Eco-friendly and renewable energy due to their high energy density, zero emissions, and relatively low operating temperature. However, the high cost, low electrocatalytic activity and stability of common Pt catalyst in used DMFCs. To overcome these problems, many efforts have been attempted with various methods. In various carbon materials, the platinum catalyst of the functionalized carbon nanotube has a small particle size and wide dispersion, so that methanol oxidation occurs on a large surface, and higher performance is expected due to the interaction of the surface-modified carbon nanotube and graphene. The synthesis of a composite material based on the modified carbon nanotube support can be extensively used as a battery electrode material and can be applied as an appropriate research topic as a catalyst support for a fuel cell. The preliminary electrochemical property had been performed and analyzed. |
