Abstract

It is generally recognized that H2O adsorption on a porous material would inhibit H2adsorption. However, this paper reports that stable H2O-functionalized zeolitic Zn(2-methylimidazole)2framework (ZIF-8), which was obtained by the simple water treatment of ZIF-8 at ambient temperature, can increase its H2adsorption heat from 5.2 to 10.1 kJ/mol. As a result, the reversible H2capacity at ambient temperature increased by 77%. This indicates that H2O functionalization provides a novel approach to enhance ambient-temperature hydrogen storage in ZIF-8 and other metal-organic frameworks.
