Highly Selective CO₂ Capture by a Flexible Microporous Metal–Organic Framework (MMOF) Material

Abstract

Caught in a CO2 trap: A highly flexible microporous metal–organic framework material exhibits a remarkable ability to capture and separate carbon dioxide from other small gases, such as N2, H2, CH4, CO, and O2, with separation ratios of 294, 190, 257, and 441 for CO2/N2, CO2/H2, CO2/CH4, and CO2/CO, respectively, at 0.16 atm and 25 °C, and 768 for CO2/O2 at 0.2 atm and 25 °C.
