Summary: In this study, organosilica membranes with good hydrothermal stability were prepared by incorporating ZIF-7 nanoparticles into 1, 2-bis(triethoxysilyl)ethane (BTESE) networks to improve the H-2/CO2 permselectivity. The effect of inorganic fillers was investigated by adjusting the doping content of ZIF-7 nanoparticles. The hybrid membranes showed a decrease in H-2/CO2 permselectivity with increasing nanoparticle doping content.
