Hello, We plan to expand the scope of the Membrane Gas Separations wikipedia page to include an in-depth, up-to-date discussion of membranes for CO2 separation. The current page only discusses polymeric and nanoporous membranes and lacks discussion of zeolitic, silica, perovskite oxide membranes, and more. In addition, there is a lack of meaningful discussion which summarizes the current state and future directions of CO2 capture by membrane processes. We will add sections on inorganic and hybrid membranes. Our additions will include information on material development and recent findings from mechanistic investigations.
