Membrane-based direct air capture (m-DAC) has recently been introduced as a simple, scalable, and environmentally friendly method to CO2 from the atmosphere. The captured is considered be carbon source for chemical reduction other value-added chemicals. However, of disrupted by any O2 in gas. Therefore, membranes with high CO2/O2 selectivity are essential m-DAC process. In this work, we design magnetic mixed matrix (MMMs) nanoparticle (MNP) fillers polymer matrices, which exhibit room-temperature trapping gaseous within membrane achieve selectivities. We found that increased both MNP content externally applied field strength, signifying interaction paramagnetic MNP, while permeation remained unaffected. experimental results were supported our mathematical model. Overall, PolyActive-MMMs containing 40 wt % MNPs achieved highest 35 under 800 mT, corresponding enhancement 60% over pure PolyActive membranes. Our findings demonstrate potential using fields control gas transport applications require separation gases.
