Synthesis and Characterization of Metal Organic Frameworks for Gas Storage

Abstract

This research demonstrates the preparation of a metal-organic framework (MOF-199) using the solvothermal method. The solvothermal conditions for synthesis and activation were investigated by changing the synthesis time (24 - 48 h), the solvothermal temperatures (85 and 100 °C), and the effect of the ethanol: water solvent ratio (within the solvents range from 1:1 to 1:2 ratios). All synthesized samples were characterized using of x-ray diffraction (XRD), scanning electron microscopy (SEM) and specific surface area (BET). The prepared MOF-199 at the optimal conditions (100 °C for 48 h, 1:1 of the ethanol: water) has up to 5518 m2/g m2/g surface area (BET), 0.693 cm3 g−1 specific volume, a 11.8 Å porous size, and 103 crystallinity. All MOF-199 samples were activated for 21 h at 60 °C.

A modest method of synthesis Cu- based metal-organic frameworks using benzene dicarbocxylate as a ligan for promising candidate of flue gas CO2 adsorption

“…This size was smaller than the previous studies have been reported [16,17]. Meanwhile, the total crystallinity of synthesized CuBDC was 91 % which is relatively similar with what have been reported by others [18,19].…”

A kinetic study of HKUST-1 for desulfurization applications

“…The HKUST-1 was 0.7 cm 3 /g pore volume and 3400 m 2 /g and surface area that was far from Kareem's results (2902 m 2 /g ) under the same operating condations [9].…”

“…In this work, HKUST-1 was prepared based on the solvothermal method reported by Kareem et al [9]. A 0.42 g trimesic acids dissolved in 24 ml ethanol solution (de-ionized water and ethanol 1:1 vol.%).…”

Using genetic algorithms to systematically improve the synthesis conditions of Al-PMOF

“…23 There are a considerable number of parameters that can influence the reaction and its outcome (i.e., solvents, pH, reagents concentration, reaction time, temperature, pressure, etc. ), 24,25 and the optimization of these conditions for new or established MOFs is often laborious, expensive and time-consuming. 26,27 While conventionally, the optimization of these parameters rest on the chemical intuition of individuals, novel approaches are needed to tackle the extensive diversity in chemistry of MOFs.…”
