In this study, four different iron-based metal–organic frameworks (Fe-MOFs) were synthesized by growing them in situ on carboxylated cotton fabrics. Scanning electron microscopy (SEM), X-ray diffraction (XRD), and X-ray photoelectron spectroscopy (XPS) were employed to conduct a comprehensive characterization of the Fe-MOFs. The dye removal rate of Fe-MOF@Cotton was meticulously determined by comprehensively investigating various factors including the concentration of the dye and hydrogen peroxide (H₂O₂), the pH value of the solution, and the temperature. Extensive catalytic degradation experiments were conducted to assess the performance of Fe-MOF@Cotton. The results vividly demonstrated that Rhodamine B (RhB) was photocatalytically degraded by Fe-MOF@Cotton with remarkable efficiency in the presence of H₂O₂. Notably, the four MOF fabric composites were capable of degrading over 97% of RhB with a concentration of 20 mg/L. Moreover, these composites exhibited excellent reusability, strongly indicating their significant potential for application in the dye wastewater treatment industry.

It is therefore important to develop new materials for the adsorption or degradation of these compounds using various techniques. In this study, two novel magnetic recyclable composite catalysts Zr–NiFe₂O₄@ZIF-67 and Zr–NiFe₂O₄@ZIF-8 were synthesized. These catalysts degraded tetrachlorobisphenol A (TCBPA) in water by activating peroxydisulfate (PDS)/peroxymonosulfate (PMS), respectively. The results show that the Zr–NiFe₂O₄@ZIF-67-5%/LED/(NH₄)₂S₂O₈ system can degrade 95% of TCBPA (20 mg/L) within 30 min, whereas the Zr–NiFe₂O₄@ZIF-8-10%/LED/KHSO₅ system degrades 90% of TCBPA within 30 min. In instances of metal leaching at low concentrations, nickel and iron ions declined to 0.008 mg·L⁻¹, TCBPA exhibits highly efficient and sustainable catalytic properties, maintaining over 80% efficacy across six cycles. The online infrared test experiment results showed the major functional groups disappearing within approximately 130 s. The results of electron paramagnetic resonance and free-radical-quenching experiments showed that SO₄˙⁻, ˙OH, ¹O₂, and O₂˙⁻ were involved in the degradation of TCBPA. The possible degradation paths are isomerization polymerization, dechlorination, hydroxylation, ring-opening by oxidation, and further transformation into small molecules of acids, aldehydes, alcohols and other compounds. Thus, in this study, a reliable technique for the degradation of halogenated bisphenol compounds is developed.
