Abstract
AbstractThe presence of dyes in wastewater poses a significant environmental challenge due to their permanence toxicity and potential to harm ecosystems. Because of their high porosity and adjustable characteristics, metal‐organic frameworks (MOFs) have become attractive materials for effective dye removal. Among various MOFs, zeolitic imidazolate frameworks (ZIFs) have garnered significant attention, especially ZIF‐8, for its excellent stability, significant porosity, adjustable pore size and remarkable adsorption capacity. This review article provides a comprehensive overview of recent advances in the implementation of ZIF‐8 and its composites for the removal of pollutants from wastewater. The various synthesis methods, structural characteristics and dye adsorption performance of ZIF‐8 and its composites are discussed. Furthermore, impact of the different factors such as pH, temperature, dye concentration, contact time etc. were also highlighted. Moreover, the detailed adsorption mechanism was also discussed. Finally, the current challenges and future perspectives in the production of materials based on ZIF‐8 for the removal of dyes were also presented.
