Preparing PAN/MOF nanofiber composite by electrospinning method for carbon dioxide adsorption

The purpose of this work is to provide an efficient adsorbent in its stabilized form. In the present study, MOF particles were synthesized using solvothermal method and identified by FTIR and XRD devices. After stabilization in the form of a PAN based electrospun fiber, studying morphology, distribution of the particles and its map on SEM images, thermal resistance in TGA analysis, measurement of the surface area by BET device and carbon dioxide adsorption with a new method at constant pressure were investigated. Various conditions such as gas content, removal time, the adsorbent mass and mixing extent were optimized by recording the initial and final adsorbate values in gas chromatography with thermal detector (under optimal conditions the adsorption rate is reported to be up to 58%). The isotherm data shows the most agreement with the Freundlich isotherm with KF equal to 1.32 unit. Moreover, the adsorption process kinetics were examined which the results indicate compliance with the pseudo-second-order model.
