摘要

A novel Zr-fumarate (Zr-fum) metal organic framework was synthesized by the reaction of zirconium chloride and fumaric acid under solvothermal conditions without a formic acid modulator. The synthesized material was characterized by the powder X-ray diffraction, Thermogravimetric Analysis (TGA), Scanning Electron Microscopy (SEM), Fourier Transform Infrared Spectroscopy (FT-IR), and Brunauer-Emmett-Teller (BET) techniques. The results of powder XRD showed the presence of amorphous and crystalline phases. The surface area and average pore diameter of the material were found to be 205.49 m2/g and 2.12 nm, respectively, and TGA showed that the material was stable up to 300°C. The CO2 adsorption properties of the Zr-fum MOF revealed an uptake of 8 wt% at room temperature (25°C) and atmospheric pressure. The cyclic CO2 sorption study showed the complete recyclability of the synthesized material, suggesting that the material has potential for use in gas sorption and separation.
