Abstract

The prepared microporous hydrotalcite (HT)–silica membrane was found to exhibit the molecular sieving characteristic of pristine silica material and high $$\mathrm{CO}_{2}$$CO2 adsorption capacity of HT. The combined properties made enhanced $$\mathrm{CO}_{2}$$CO2 permeability and separability from $$\mathrm{CH}_{4}$$CH4 possible. The gas transport in the membrane was predominantly surface adsorption. The porous membrane overcame the Knudsen limitation and yielded the highest separation selectivity of 120 at 40 % CO₂ operating temperature, and 100 kPa pressure difference.
