Separation performance of CO2 through Supported Magnetic Ionic Liquid Membranes (SMILMs)

► CO2 separation using Supported Magnetic Ionic Liquid Membranes (SMILMs) is studied. ► Membrane stability, gas permeability and selectivity towards CO2 is evaluated. ► Both supports including MILs ensure their operation at real process pressure. ► Higher selectivity towards CO2 may indicate a potential application. ► Application of an external magnetic field could enhance CO2 separation performance.
