Oct 15, 2024 · Metal organic frameworks (MOFs)-based composites have the advantages of large specific surface area (SSA), adjustable structure, rich active sites, and easy functionalization, which have broad application prospects in photocatalytic H2 production.

May 10, 2014 · Metal-organic frameworks can store substantial amounts of hydrogen at cryogenic temperatures. The MOF, NU-100 (NU = Northwestern University), for example, was reported to store 99.5 mg g −1 (approximately 9 wt.%) hydrogen at 56 bar and 77 K [32].

Sep 27, 2023 · A detailed analysis of the top selected MOFs, their adsorption isotherms, and MOF design rules to enhance H 2 adsorption are presented. We found a functionalized IRMOF-10 with an enhanced H 2 adsorption increased by ∼6 times compared to that of pure IRMOF-10 at 1 …

Nov 1, 2023 · The total gravimetric H 2 uptake is 17.6 wt% at 77 K, higher than MOF-177(7.5 wt%), MOF-200(16.3 wt%), and MOF-205(12.3 wt%). Mg-MOF-74 is also a representative MOF, which has a hexagonal one-dimensional channel, and its pores are decorated with unsaturated Mg 2+ coordination sites.

Jul 9, 2021 · A strategy that improves packing efficiency and volumetric hydrogen gas storage density dramatically through engineered morphologies and controlled-crystal size distributions is presented that holds promise for maximizing storage capacity for a given MOF.

Apr 5, 2019 · Three MOFs with capacities surpassing that of IRMOF-20, the record-holder for balanced hydrogen capacity, are demonstrated: SNU-70, UMCM-9, and PCN-610/NU-100. Analysis of trends reveals the...

Sep 7, 2018 · This study represents the first high-throughput computational screening of the most recent MOF database for membrane-based H2/CH4 sepn. and microscopic insight provided from mol. simulations will be highly useful for the future design of …

Jun 2, 2024 · In this review we explore the current methods used (i. e., open-metal sites, alkali dopants and hydrogen spillover) for promoting strong adsorption within MOFs. Further we discuss MOF-based materials with respect to the technical aspects of …

Mar 5, 2024 · Metal–organic frameworks (MOFs) incorporating open metal sites (OMS) have been identified as promising sorbents for many societally relevant-adsorption applications including CO2 capture, natural gas purification and H2 storage.

Metal–organic frameworks (MOFs) have significant potential for hydrogen storage. The main benefit of MOFs is their reversible and high-rate hydrogen adsorption process, whereas their biggest disadvantage is related to their operation at very low temperatures.
