“…Its adsorption capacity was improved by roughly 80% and 90% in the batch and continuous systems, respectively, when the starting dye concentration was increased from 2 to 8 mg L −1 . 83 In another report, 84 a TiO 2 @Cu-MOF nanocomposite was synthesized using copper nitrate trihydrate as the copper source and the effect of the TiO 2 loading on the adsorption of rhodamine B was investigated. The outcomes demonstrated that the composite material not only exhibited good rhodamine B degradability (98.03% of the dye was removed after 120 min) but also exhibited a good cycle performance.…”

“…Conversely, a rise in the catalyst's concentration hinders the effective assimilation of light within the solution. Comparable findings were documented for MOF as an "eco-friendly catalyst" in the photocatalytic breakdown of organic dyes like rhodamine B and crystal violet in aqueous environments [50,51].…”

Metal-organic frameworks (MOFs) have received significant attention for their use as photocatalysts and photocatalyst supports. These materials have a number of benefits, including stability, catalyst reusability, tunability, and the capacity for post-reaction separation. Here, the potential applications of UiO-66-NDC (1,4-Naphthalenedicarboxylic acid) as a photocatalyst for the degradation of reactive orange 16 (RO16), methyl orange (MO), and rhodamine B (RhB) were investigated. Due to its large surface area, adjustable characteristics, stability, effective light absorption, capacity for charge separation, and adaptability in design, UiO-66-NDC was chosen for photocatalytic dye degradation. A solvothermal process was used to synthesize the UiO-66-NDC, and methods including X-ray diffraction (XRD) and scanning electron microscopy (SEM) were used to characterize its structure. The zeta potential was used to determine the surface charge. In order to conduct the photocatalytic tests, dye solutions with defined concentrations were exposed to UVA light irradiation in the presence of UiO-66-NDC. UV-visible spectroscopy was used to monitor the degradation process, which made it possible to calculate the degradation rate constants and the percentage of dye removal. The removal efficiency of adsorption, which was also examined, was at a minimum (17% for RO16, 48% for MO, and 25% for RhB). The degradation of the dyes by UiO-66-NDC showed excellent photocatalytic activity, with degradation rates for RO16, MO, and RhB of 93%, 94%, and 91%, respectively, and good reusability. The research determined that 300 mg/L of catalyst was the ideal level. Three successive cycles of using UiO-66-NDC as a catalyst have demonstrated its reusability. It was possible to remove 97% of RO16, 99% of MO, and 95% of RhB at a high starting dye concentration (20 mg/L).

“…Due to its special features, including high porosity, high specific surface area and catalytic efficiency, as well as magnetic and electrochemical capabilities, MOF has many applications, namely adsorption applications. MOF has attracted a lot of interest in the field of organic dye removal, for example, Zn-MOF [2] , Al-MOF [3], Fe-MOF [4] and Cu-MOF [5].…”

Water is an extremely important resource for human sustainable development. Currently, along with the development of industrialization and modernization, environmental pollution in general and water environment is a burning problem for us. Textile dyeing companies as well as other chemical companies consume large quantities of dyes, resulting in highly soluble dyes that become a major source of water pollution. Organic dyes are not easily decomposed, the discharge of untreated wastewater containing many dyes into the aquatic environment causes serious consequences for the ecosystem as well as human
