چکیده مقاله

Metal-organic frameworks (MOFs) represent a class of crystalline, porous materials constructed from metal ions or clusters coordinated with organic linkers, forming highly ordered, tunable structures with exceptional surface areas and porosity, making them versatile for energy and environmental applications [1]. These frameworks exhibit semiconductor-like properties due to charge transfer between metal nodes and ligands, enabling efficient light harvesting and electron-hole separation under UV or visible irradiation, which positions MOFs as one of the most promising photocatalysts for sustainable remediation processes. The synthesis of MOFs typically involves solvothermal and hydrothermal methods, in which metal salts and organic ligands in solvents such as DMF and water produce crystalline products. Alternative approaches include the use of microwave, mechanochemical, or room temperature methods to increase scalability and control morphology [2]. MOFs offer a green, low-cost pathway for environmental remediation, with ongoing research focusing on defect engineering and composite designs to optimize quantum efficiency and real-world scalability [3]. By combining strong adsorption of pollutant molecules such as dyes with photocatalytic activity under UV or visible light, MOFs generate reactive oxygen species and other radical scavengers that degrade anionic dyes into smaller, less toxic products, often achieving high removal efficiencies, while maintaining recyclability and structural stability over multiple cycle. The aim of this research is to enhance the photocatalytic activities of MOFs using a heterostructure based on Fe and Ni metals (Scheme).
