In the current work, synthesised Magnesium Tetraphenylporphyrin (MgTPP) functionalised with ethylenediamine (EDA) loaded onto Polyetherimide (PEI) nanofibers were fabricated by means of electrospinning. The ability of the developed membrane for potential CO 2 and PM 2.5 capture was evaluated. Ethylenediamine, the chelating agent was loaded onto the fibrous structure; the introduced amino group pendants captured CO 2 molecules effectively. Structural evidence was revealed by infrared spectroscopy. The average diameter of the amino modified MgTPP/PEI nanofibers was found to be in the range of 1.2–1.4 μm and possessed a high thermal stability of 411 °C. The contact angle measurements proved the hydrophilic nature of the filter. The fibrous membrane possessed high CO 2 and PM 2.5 filtration capacity of 74% and 81% respectively with extraordinary non-zero dust loading capacity. Finally, the significance of the addition of EDA for CO 2 adsorption was proved statistically.
