Multi-walled carbon nanotubes (MWCNTs) incorporated MIL-53-Cu composite MOF material (MWCNT@MIL-53-Cu) has been synthesized by adding purified multi-walled carbon nanotube (MWCNT) in situ during the synthesis of MIL-53-Cu. Resulting sample was characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), Brunauer–Emmet–Teller (BET), and FT-IR analysis. Methane sorption capacities of MIL-53-Cu were observed to increase from 8.52 to 13.72 mmol g-1 at 298 K and 35 bar. The increment in the methane uptake capacities of composite MOF materials was attributed to the decrease in the pore size and enhancement of micropore volume of MIL-53-Cu by multi-walled carbon nanotube incorporation.

Iron terephthalate, MOF-235, metal-organic framework synthesized hydrothermally and was used for gas adsorption. Resulting sample was characterized by X-ray diffraction (XRD), Brunauer–Emmet–Teller (BET) and FT-IR analysis. Adsorption properties of CH4, H2 and CO2 on MOF-235 were investigated by volumetric measurements. The absolute adsorption capacity was found in the order of CH4 >> H2 > CO2. The high CH4 adsorption capacity of MOF-235 was attributed to the high pore volume and large number of open metal sites. The high selectivity for CH4 over CO2 (14.7) and H2 (8.3), suggests that MOF-235 is a potential adsorbent for the separation of CH4 from gas mixtures.
