A Lightweight Beryllium Metal-Organic Framework for Combined Physical and Chemical Hydrogen Storage.

ABSTRACT: In this work, we report the synthesis and structural characterization of the beryllium-based metal-organic framework of general formula [Be₄O-(BDC-NH₂)_2.5(OAc)] (Be_BDC_NH ₂ ), designed for combined physical and chemical hydrogen storage applications. The material was extensively characterized through a plethora of solid-state techniques (including less conventional ⁹Be NMR-MAS spectroscopy). Structural analysis by X-ray powder diffraction confirmed the formation of a crystalline porous framework of fcu topology isostructural to MOF-5 and to MOF-5-(Be), while thermogravimetric studies revealed remarkable thermal stability up to 830 K. Nitrogen adsorption measurements demonstrated a high specific surface area (2264
