Synthesis and structural characterization of Co-BTC metal-organic framework

Metal-organic framework materials based on cobalt(II) ions and 1,3,5-Benzenetricarboxylic acid were synthesized by microwave and hydrothermal methods. The time to synthesize materials by hydrothermal method is much longer than by that of the microwave method. Synthesized materials were characterized by scanning electron microscopy (SEM), X-ray diffraction (XRD), infrared spectroscopy (IR), and Brunauer-Emmett-Teller (BET) surface area. The results showed that the morphology of the Co-BTC is a rod-shaped crystal with length between 5-10 μm. The specific surface area of the material synthesized by microwave and hydrothermal methods is 99.085 m2/g and 45.348 m2/g, respectively.
