Structural Design and Energy and Environmental Applications of Hydrogen‐Bonded Organic Frameworks: A Systematic Review

Advanced Science, Journal Year: 2024, Volume and Issue: 11(22)

Published: April 22, 2024

Abstract Hydrogen‐bonded organic frameworks (HOFs) are emerging porous materials that show high structural flexibility, mild synthetic conditions, good solution processability, easy healing and regeneration, recyclability. Although these properties give them many potential multifunctional applications, their unstable due to the presence of only weak reversible hydrogen bonds. In this work, development history synthesis methods HOFs reviewed, categorize design concepts strategies improve stability. More importantly, significant latest HOF‐related research for addressing energy environmental issues, work discusses advances in storage conversion, substance generation isolation, detection degradation transformation, biological applications. Furthermore, a discussion coupling orientation HOF cross‐cutting fields environment is presented first time. Finally, current challenges, opportunities, advance applications discussed.

Carbon capture and sequestration (CCS) in geological formations is a prominent solution for reducing anthropogenic carbon emissions mitigating climate change. The capillary trapping of CO2 primary mechanism governed by the pressure difference between wetting nonwetting phases porous rock, making latter key input parameter dynamic simulation models. During CCS operational process, however, prone to contamination impurities from various sources such as surfaces (e.g., pipelines tanks) subsurface existing natural gas). Such can strongly influence overall wettability, storage capacity, containment security. Hence, present study uses nuclear magnetic resonance (NMR) core flooding technique investigate compare residual saturations pure CO2, N2, 50:50 CO2/N2 mixture an Indiana limestone. longitudinal transverse relaxation times (T1 T2) are measured examine displacement process pore network, evaluated at scale determinant field-scale flow behavior.

In CO2-brine system, intermolecular interplay CO2-enriched brine higher ratio significantly reduces hydrophilicity Furthermore, T2 distribution reveals occurrence preferential water into large pores (r > 1 µm) intermediate (0.03 µm < r µm), whereas remains immobile smaller 0.03 µm). insignificant saturation CO2-N2 indicates potential allow phase without capacity. Thus, work provides comprehensive information on impact injection scale, thereby aiding development other applications enhanced oil recovery (EOR).
