Mechanochemical Dual-Metal Modification of CuBTC Metal-Organic Frameworks for Enhanced Hydrogen Storage.

ABSTRACT: Metal-organic frameworks (MOFs) are promising materials for hydrogen storage due to their high specific surface area and structural tunability. In this study, we provide the first demonstration of enhanced hydrogen storage performance in a CuBTC (also known as HKUST-1) MOF by incorporating nickel and magnesium through a combination of in situ and postmodification solvent-free mechanochemical ball milling. A comprehensive combination of structural and adsorption-desorption characterization is employed to examine and understand the impact of Ni²⁺ and Mg²⁺ divalent metal ions through in situ and postmodification methods. In general, the post-Ni-modification method achieved higher hydrogen storage capacities than in situ-Ni-modification routes. The po
