Abstract

Through a combination of many analytical approaches, we show that a metal organic nanotube (UMON) displays selectivity for H2O over all types of heavy water (D2O, 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.
