Neon (Ne) is an expensive noble gas with commercial interest, which is why systems for Ne storage and delivery are useful tools for its more efficient utilization. Although adsorption-based technologies are potential candidates for the development of such systems, there have been few research efforts on the study of Ne adsorption equilibria on porous solids. Metal-organic frameworks (MOFs) are a recent class of promising porous materials for adsorptive gas storage. In the present work, Ne adsorption in two of the most well-known MOF materials - HKUST-1 and UiO-66 - has been evaluated experimentally over unusually wide pressure and temperature ranges: 0-70 bar, 77-400 K for HKUST-1 and 0-100 bar, 77-500 K for UiO-66. HKUST-1 has higher Ne adsorption capacity per unit weight than UiO-66, whereas per unit volume the two materials perform similarly. Moreover, the isosteric heats for Ne adsorption on HKUST-1 and UiO-66 have roughly the same order of magnitude (3-6 kJ/mol).
