High Uptakes of CO2 and CH4 in Mesoporous Metal—Organic Frameworks MIL-100 and MIL-101

Abstract

Mesoporous MOFs MIL-100 and MIL-101 adsorb huge amounts of CO₂ and CH₄. Characterization was performed using both manometry and gravimetry in different laboratories for isotherms coupled with microcalorimetry and FTIR to specify the gas—solid interactions. In particular, the uptake of carbon dioxide in MIL-101 has been shown to occur with a record capacity of 40 mmol g⁻¹ or 390 cm³_STP cm⁻³ at 5 MPa and 303 K.
