Fe/C hybrid carbon membranes were designed and prepared by incorporating ferrocene into the precursor of carbon membrane and then by carbonization under high temperature.Effects of ferrocene quantities added on the gas permeability of the hybrid carbon membrane were investigated.The prepared hybrid carbon membrane was characterized by TG

ATR-FTIR

XRD and TEM.The ferrocene quantities added have a remarkable effect on the gas permeability of carbon membrane.The gas permeability of the membrane increases

while the selectivity decreases

with the increase of the ferrocene quantities added. The hybrid carbon membrane shows an excellent gas separation performance when the addition of ferrocene is 15% where the gas permeabilities of pure gases such as H2
