Customised ultra-microporous filler for efficient CO2/CH4 separation in mixed matrix membranes
Separation and Purification Technology（2024）
Abstract
•In situ ion activation method for the preparation of porous carbon spheres IE-HC.•The formation of 'knot-like' structures of polymer chains within the membrane increases the mechanical properties.•Interconnected ultra-micropores for excellent CO2/CH4 separation performance.•Pore structure control provides a strategy for gas membrane separation.
