Abstract
Nitrogen storage capacity was investigated on a highly efficient adsorbent nanoparticle called Metal Organic Framework (MOF). A copper-based MOF called MOF-199 has been synthesized from subsequent reaction of Copper nitrate (10 wt.%), Trimesic Acid (8 wt.%) and Triethylamine (0.3 wt.%). TEA served as a deprotonating agent to form small particles. The reactants were mixed in a solution of Dimethylformamide (DMF), Ethanol and Deionized water (1:1:1) and vigorously sonicated for an hour at room temperature. This yielded single blue octahedral MOF crystals which were later washed with mother solution and extracted via centrifuge. The MOFªs were later activated for gas adsorption by heating them in vacuum at 120è_C for 18 hours. SEM images of the as-synthesized MOF particles showed an average diameter of 100-200 nm. Powder X-ray Diffraction (XRD) of the samples was performed to determine the crystalline structure and porosity of the MOF. BET analysis of the MOF particles gave a surface area of 1800-2000 m2/gm, which is considered to be extremely effective for gas adsorption purpose. Nitrogen adsorption test of the MOFªs gave a total gas uptake of 650 cm3/gm. Further experimentation will be focused on achieving even larger surface area by decreasing the particle size and increasing the porosity. Breakthrough CO2 adsorption experimentation will be performed to analysis the gas selectivity of the MOFªs. The nano-scaling of the MOF particles will have a significant impact on incorporating these with electrospun polymeric fibers which will be investigated as well.
