Delaminated or multilayer Ti3C2TX-MXene-incorporated polydimethylsiloxane mixed-matrix membrane for enhancing CO2/N2 separation

Membrane-based gas separation is currently attracting tremendous attention as this unit operation has been considered as one of the available strategies that can contribute toward carbon neutrality. Nevertheless, polymeric membranes suffer from material-related limitation, namely the permeability/se...
