The attention to direct methanol fuel cells (DMFCs) as sources of clean energy and mobile power generation has been increased in the industry. Platinum catalyst have been used as cathode and anode electrodes in fuel cells. However, some issues such as poor methanol oxidation kinetics, high-cost, durability of Pt-based catalyst, CO-poisoning, prevent their widespread commercialization. In this case of Pt-c(NH2-MIL-101)@CNT, an amine-functionalized MIL-101 and a platinum catalyst supported on a nitrogen-doped carbon nanotube composite were prepared, and the electrochemical properties were investigated. Metal-organic framework provides an area for supporting platinum nanoparticles, and carbon nanotubes (CNTs) are used as electron transfer pathway. The prepared composite corresponded to the most active electrocatalyst. |
