Recent development of metal-organic framework 5 adsorbents for organic dye removal from aqueous solution

The development of novel materials is critical for the sustainable improvement of adsorption of organic dye contaminants. Metal-organic frameworks (MOFs) have recently gained a lot of attention due to their unique features. One of the most representative MOFs is MOF-5 [Zn4O(BDC) (3)]. This study compiles the recent research on the adsorptive removal of different organic dyes from aqueous solutions using pristine and modified MOF-5. The history and background of MOFs together with synthesis methods and characterization were briefly discussed. The development of MOF-5-based materials and their effectiveness under various process parameters in organic dyes adsorption were briefly highlighted. The discussion related to the characterizations of MOF-5 was also included. This review also outlined several challenges that the scientific community should investigate further to improve MOF-5 applications in organic dye adsorption. This review provides a valuable resource for researchers intending to use MOF-5 to remove organic dye from aqueous solutions.
