dc.description.abstract | Hydrogen storage is crucial in the shift toward a carbon-neutral society, where hydrogen serves as a pivotal renewable energy source. Utilizing porous materials can provide an efficient hydrogen storage solution, reducing tank pressures to manageable levels and circumventing the energy-intensive and costly current technological infrastructure. Herein, two highly porous aromatic frameworks (PAFs), C-PAF and Si-PAF, prepared through a Yamamoto C & horbar;C coupling reaction between trigonal prismatic monomers, are reported. These PAFs exhibit large pore volumes and Brunauer-Emmett-Teller areas, 3.93 cm3 g-1 and 4857 m2 g-1 for C-PAF, and 3.80 cm3 g-1 and 6099 m2 g-1 for Si-PAF, respectively. Si-PAF exhibits a record-high gravimetric hydrogen delivery capacity of 17.01 wt% and a superior volumetric capacity of 46.5 g L-1 under pressure-temperature swing adsorption conditions (77 K, 100 bar -> 160 K, 5 bar), outperforming benchmark hydrogen storage materials. By virtue of the robust C & horbar;C covalent bond, both PAFs show impressive structural stabilities in harsh environments and unprecedented long-term durability. Computational modeling methods are employed to simulate and investigate the structural and adsorption properties of the PAFs. These results demonstrate that C-PAF and Si-PAF are promising materials for efficient hydrogen storage. The two highly porous aromatic frameworks (PAFs), C-PAF and Si-PAF, synthesized from trigonal prismatic monomers, exhibit unmatched porosities among the porous organic materials. These materials display record-breaking gravimetric hydrogen delivery capacities, combined with substantial volumetric delivery capacities, surpassing existing benchmark materials. Additionally, these PAFs demonstrate remarkable structural stability and long-term durability, attributed to their robust C & horbar;C covalent bonds. image | - |
