A significant enhancement of water vapour uptake at low pressure by amine-functionalization of UiO-67

The functionalization of UiO-67 with -NH2 groups enhances CO2 and CH4 adsorption at 1 bar and 298 K and positively influences the framework's interaction with water as evidenced by the significant enhancement of water vapour adsorption at 0.1 < P/P0 < 0.3 and 298 K.
