Polyethersulfone based MMMs with 2D materials and ionic liquid for CO, N and CH separation.

Increasing concerns on global warming and climate change have led to numerous attempts on developing new membrane materials to reduce excessive CO emission into the atmosphere. In the present work, we focused on the separation of CO from gas mixtures through two-dimensional (2D) materials based mixed matrix membranes (MMMs). The ionic liquid (IL) 1-Ethyl-3methylimidazolium bis (trifluoromethylsulfonyl) imide together with different weight fractions (0.
