CO2 capture of InOF-1 was enhanced 3.6-fold, at 1 bar and 30 °C, by confining EtOH within its pores. Direct visualisation by single crystal X-ray diffraction revealed that EtOH divides InOF-1 channels in wide sections separated by "bottlenecks" caused by EtOH molecules bonded to the μ2-OH functional groups of InOF-1.

The water-stable material NOTT-401 was investigated for CO 2 capture under humid conditions. Water adsorption properties of NOTT-401 were studied, and their correlation with CO 2 sequestration at different relative humidities (RHs) showed that the CO 2 capture increased from 1.2 wt % (anhydrous conditions) to 3.9 wt % under 5% RH at 30 °C, representing a 3.2-fold improvement.

Upon the removal of coordinated H2O and DMF molecules to the paddlewheel of MOP 4 (followed by FTIR), it showed very interesting CO2 capture properties at 196 K.
