ABSTRACT As the amount of tetrachlorobisphenol A (TCBPA) that causes potential adverse effects on human health in environment is continually increasing. It therefore important to develop new materials for adsorption or degradation these compounds using various techniques. In this study, two novel magnetic recyclable composite catalysts Zr–NiFe 2 O 4 @ZIF‐67 and @ZIF‐8 were synthesized. These degraded water by activating peroxydisulfate (PDS)/peroxymonosulfate (PMS), respectively. The results show @ZIF‐67‐5%/LED/(NH ) S 8 system can degrade 95% TCBPA (20 mg/L) within 30 min, whereas @ZIF‐8‐10%/LED/KHSO 5 degrades 90% min. instances metal leaching at low concentrations, nickel iron ions declined 0.008 mg·L −1 , exhibits highly efficient sustainable catalytic properties, maintaining over 80% efficacy across six cycles. online infrared test experiment showed major functional groups disappearing approximately 130 s. electron paramagnetic resonance free‐radical‐quenching experiments SO ˙ − ˙OH, 1 involved TCBPA. possible paths are isomerization polymerization, dechlorination, hydroxylation, ring‐opening oxidation, further transformation into small molecules acids, aldehydes, alcohols other compounds. Thus, a reliable technique halogenated bisphenol developed. Overall, photocatalytic organic pollutants utilizing polymetallic composites as represents an innovative approach treatment, demonstrating enhanced activity recyclability, with promising prospects significant advancements both theoretical research practical applications.
