Metal-organic frameworks for H2 and CH4 storage: Insights on the pore geometry-sorption energetics relationship

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.
