By filling a PDMS top layer with porous carbon–silica microspheres, defect-free mixed matrix membrane was created notable CO2 reverse selective separation properties. For the of over H2 at room temperature and 10 bar inlet pressure, these membranes demonstrate high gas fluxes up to 3 × 10−7 mol cm−2 s−1, in combination ideal factors range 6 9. The present data signify an important step forward removal from using strategy. Moreover, they elucidate potential such emerging field separation.
