•New composite materials have been synthesized based on MCM-41 and Cu(BDC) MOF.•Synthesized composites were studied for selective adsorption of CO2 over CH4.•Composites were synthesized in one pot method by using microwave radiation.•The studies proved composite durability for physical adsorption of CO2.•The composite demonstrated an improved CO2/CH4 selectivity about 30% than MCM-41.
The MCM-41@ Cu(BDC) composite material was synthesized via a facile and fast microwave method. MCM-41 was used as matrix which composed by Cu(BDC) MOF. The effect of molar ratio of the metal salt to MCM-41 substrate was investigated. The synthesized composites were characterized by means of FTIR analysis, X-ray diffraction (XRD), Scanning electron microscopy (SEM), Thermogravimetric analysis (TGA), N2 adsorption-desorption isotherms and Transmission electron microscopy (TEM). The adsorption capacities of the samples were measured by a volumetric method at ambient temperature and the pressure range of 1–25 bar. The composite material with molar ratio of 1:8 (metal ion: MCM-41) demonstrated a 30% increase in CO2/CH4 selectivity and 20% increase in adsorption capacity compared to MCM-41. The stability investigation of the composite in consecutive adsorption-desorption cycles showed no significant loss in adsorption capacity.
