The escalating menace of environmental points to each nature and humanity over the previous twenty years underscores the urgency of addressing environmental pollution. Metallic–natural frameworks (MOFs) have emerged as extremely promising supplies for tackling these challenges. Since their rise in recognition, in depth analysis has been carried out on MOFs, spanning from design and synthesis to a big selection of purposes, equivalent to environmental remediation, gasoline storage and separation, catalysis, sensors, biomedical and drug supply methods, power storage and conversion, and optoelectronic units, and so on. MOFs possess a mess of advantageous properties equivalent to massive particular floor space, tunable porosity, numerous pore constructions, multi-channel design, and molecular sieve capabilities, and so on., making them notably engaging for environmental purposes. MOF-based composites inherit the superb properties of MOFs and likewise exhibit distinctive physicochemical properties and constructions. The tailoring of central coordinated metallic ions in MOFs is essential for his or her adaptability in environmental purposes. Though many evaluations on monometallic, bimetallic, and polymetallic MOFs have been printed, few evaluations specializing in MOF-based composites with monometallic, bimetallic, and multi-metallic facilities within the context of environmental pollutant therapy have been reported. This overview addresses this hole by offering an in-depth overview of the current progress in MOF-based composites, emphasizing their purposes in hazardous gasoline sensing, electromagnetic wave absorption (EMWA), and pollutant degradation in each aqueous and atmospheric environments and highlighting the significance of the quantity and kind of metallic facilities current. Moreover, the varied classes of MOFs are summarized. MOF-based composites display important promise in addressing environmental challenges, and this overview supplies a transparent and beneficial perspective on their potential in environmental purposes.
