Cobalt dopping Fe-MIL-88B were successfully synthesized -in solvothermal procedure using DMF as solvent and with/without NaOH. The samples were characterized using SEM, BET and TGA techniques. The partly substitution of Fe by Co does not change the octahedral shape of their parent Fe-MIL-88B. Crystallizations conducted in NaOH medium, however, results in rod like with 2-end octahedral shape crystals. The BET specific surface area is 139cm2/g. The TGA data indicated that the presence of Co resulted in an increase in thermal stability of synthesized samples compared to parent Fe-MIL-88B. The CO2 adsorption isotherms in Fe-MIL-88B-Co samples were measured volumetrically at five temperatures:278K, 288K, 298K, 308K, 318K. The obtained results showed that Fe-MIL-88B-Co is a potential adsorbent with a maximum adsortption capacity of 1.2312 mmol/g (at T= 278K). The sample synthesized in alkali medium exhibited a better adsorbent for CO2 storage. Keywords MIL, adsorption, CO2 References [1] S.

Background: In today’s world, rising temperature due to global warming is caused by higher concentration of carbon dioxide (CO2) emissions in the atmosphere. Metal-Organic Framework (MOF) materials have the potential to be used in carbon dioxide capture and utilization technology. Objective: The purpose of this work is to prepare metal-organic framework materials by a benign synthesis method using water as the solvent, followed by the characterization and property evaluation for CO2 adsorption study. Methods: MIL-101-Cr metal-organic framework and its derivatives with alkali ion dopants were prepared by benign hydrothermal synthesis route, which were characterized by powder X-ray diffraction method. The adsorption isotherms of CO2 for MIL-101-Cr and its derivatives were studied to comprehend the influence of alkali dopants on CO2 sorption behaviour. The equilibrium uptakes of CO2 were further evaluated by fitting the isotherms with Langmuir, Toth and Dubinin – Astakohv adsorption models to determine the adsorption parameters. Results: The crystalline structural integrity of MIL-101-Cr is not affected by doping with alkali ions. The isosteric heat of CO2 adsorption is diminished with an increase in alkali dopant size, while the induced surface structural heterogeneity increases with increasing alkali dopant size. Conclusion: The equilibrium and thermodynamic parameters calculated from this study are useful for applications in carbon dioxide capture and utilization technology.
