Through a combination of many analytical approaches, we show that a metal organic nanotube (UMON) displays selectivity for H 2 O over all types of heavy water (D 2 O, HDO, HTO). Water adsorption experiments combined with vibrational and radiochemical analyses reveal significant differences in uptake and suggest that surface adsorption processes may be a key driver in water uptake for this material.
