Abstract
This article comprehensively reviews metal-organic framework (MOF) nanocomposites and their role in gas storage, which are considered to be one of the newest and most efficient materials for storing industrial and energy gases. Due to their high specific surface area, tunable porous structure, and good thermal and chemical stability, these materials are combined with nanoparticles to improve the adsorption capacity and selectivity of gases such as hydrogen, methane, and carbon dioxide. This study reviews the structure, synthesis methods (e.g., hydrothermal, sonochemical, etc.), storage mechanisms (physical and chemical adsorption), and applications in storing of hydrogen, methane, carbon dioxide, noble and toxic gases. MOFs are produced using various methods such as hydrothermal, sonochemical, and microwave, each of which has its characteristics. A table of storage capacities is provided for gases. In addition, the incorporation of MOFs with various nanoparticles increases their capacity and performance, and improves their stability and selectivity. The classification of MOFs (IRMOF, ZIF, MIL) and the role of nanoparticles (palladium, carbon nanotubes) are also reviewed. Despite the high potential, challenges such as production costs, stability, scalability, and environmental constraints remain. Suggestions for new research include green synthesis methods interdisciplinary collaborations and technological advances, promising a bright future for sustainable energy technologies and environmental protection.s.
