Abstract

This study aims to assess the possibility of improving H₂ and CH₄ binding affinity to the aromatic walls of a designed new Metal-Organic Framework (MOF) through simultaneous dispersive interactions. It is suggested here that desirable H₂ and CH₄ storage media at low pressures require narrow uniform pores associated with large surface area, a trade-off that is challenging to achieve.

Keywords: MOFs; dispersive interactions; hydrogen storage; metal–organic frameworks; tailored pore geometry.
