This study presents a sustainable approach for low-pressure reversible H2 storage using nickel-decorated dendritic silica with hierarchical mesoporosity (DHMS-RHA) derived from rice husk waste. DHMS-RHA was prepared as renewable precursor and decorated various loadings of non-precious Ni metal spillover-assisted storage. The exhibited well-defined morphology, revealed by SEM TEM images, excellent textural properties, BET-specific surface area 701.6 m2/g total pore volume 0.91 cm3/g. an optimum initial loading 10 wt % (DHMS-RHA-Ni10) demonstrated uptake capacity 0.128 at 298 K 1 bar. Given that DHMS-RHA-Ni10 lower specific (439.7 m2/g) compared to DHMS-RHA, this suggests under conditions, affinity micropore have more pronounced effect on enhancing adsorption than area. isosteric heats the parent ranged 6.2 8.1 kJ/mol 9.7 24.8 kJ/mol, respectively, indicating physisorption mechanism. adsorption-desorption reversibility mild conditions stable cycling performance over five consecutive cycles further supported finding. demonstrates potential developing precursors decorating it inexpensive nanoparticles enhance

Isoreticular 3D covalent organic frameworks with non-interpenetrated pcu-derived dia topology: pore regulation from micropores to mesopores

Chemical Science, Journal Year: 2025, Volume and Issue: unknown

Published: Jan. 1, 2025

A novel strategy is presented for synthesizing isoreticular 3D COFs (JUC-300 to JUC-302) using high-coordinated building blocks as binodal tetrahedral nodes, enabling tunable pore sizes (1.6–5.2 nm) and a non-interpenetrated pcu -derived dia topology.

The Role of Pore Diameter on Tuning the Hydrogen Storage Capacity of Yttrium Atom‐Decorated Covalent Organic Frameworks: A Theoretical Study

Energy Storage, Journal Year: 2025, Volume and Issue: 7(4)

Published: April 25, 2025

ABSTRACT The electronic structure and hydrogen storage properties of benzene‐based covalent organic frameworks (COFs) with pore diameters 0.53, 0.99, 1.45 nm are studied using density functional theory calculations. COFs show poor H 2 molecule adsorption properties. To enhance their properties, Y atoms decorated on the an average binding energy about 5–6 eV per atom. Each atom Y‐decorated COFs, YCOF1, YCOF2, YCOF3 effectively adsorbs six molecules −0.28, −0.34, −0.35 molecule, respectively. capacity is found to be 4.7%, 5.1%, 6.5% desorption temperatures 358, 434, 447 K, findings that a larger diameter provides more space for metal decoration thereby increases capacity. weight percentage meets target suggested by U.S. Department Energy Fuel Cells Hydrogen Joint Undertaking (FCH‐JU) in Europe.

Tuning Crystal Morphology in MOFs for Improved Hydrogen Storage

ACS Applied Nano Materials, Journal Year: 2024, Volume and Issue: 7(20), P. 23733 - 23743

Published: Oct. 15, 2024

Achieving net-zero carbon emissions by 2050 is imperative to mitigating the global climate crisis, necessitating a transition sustainable energy sources. Hydrogen, recognized for its high density, promising fuel; however, storage and transportation are challenging, development of more effective materials. Metal–organic frameworks (MOFs) possess exceptional structural integrity diversity, making them highly valuable in applications such as catalysis, separations, storage. Despite their significant potential viable materials H2 storage, poor packing powdered MOFs limits volumetric capacity. Improvement density can be achieved modifying crystal shape structure reduce void volume. In this paper, we embarked on synthesizing different nonideal shapes orientations varying ligand-to-metal ratio, which changes overall growth direction. We report engineering MIL-53-Al, focusing tuning size distribution enhance This approach allows synthesis MOF nanomaterials with surface area (up 1900 m2/g) increased (0.38 g/cm3), while preventing damage when subjected pressure compaction, thereby enhancing After tuning, capacity two best-performing samples, (MIL-53-Al)1:1 (MIL-53-Al)0.52:1, exhibited monoclinic shape, enhanced not only but also working system. Specifically, an enhancement 25% capacities compared pristine MIL-53-Al. Moreover, was estimated 37 g/L under swing (PS) conditions between 77 K/70 bar K/5 bar, surpassing 30 compressed 700-bar systems.
