Water Adsorption Properties of NOTT-401 and CO<sub>2</sub> Capture under Humid Conditions

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