Preparation and Catalytic Activity of Platinum Supported on Amine-Functionalized MIL-101 (Fe)/Nitrogen-Doped Carbon Nanotube Composite for Fuel Cells

Pt-supported on amine functionalized MIL-101 (Fe) and nitrogen doped multi-walled carbon nanotube (CNT) composites were synthesized by hydrothermal synthesis and pyrolysis process. Electrochemical properties were measured by cyclic voltammetry (CV), chronoamperometry (CA) and structural analysis was done by field emission scanning electron microscopy (FE-SEM) and Fourier transform infrared spectroscopy (FT-IR). As a result, higher electrochemical surface area (ECSA) and methanol oxidation reactions were obtained, and the electrochemical properties of Pt-c(NH 2 -MIL-101)@NCNT are better than pristine Pt-c(NH 2 -MIL-101). The enhanced activity related with the synergy effect from the higher conductivity of N-doped CNT and the better porous nanostructure of carbonized NH 2 -MIL-101(Fe).
