Effective BPA degradation in water: the integration of bimetallic UiO-66 Ce-Zr.

ABSTRACT: In this work, a bimetallic MOF UiO-66 Ce-Zr to degrade bisphenol A (BPA) in water was synthesised. The material exhibited a remarkable degradation efficiency of 84.3% under UV irradiation for 240 minutes. Combining cerium (Ce) and zirconium (Zr) in the MOF structure enhanced the catalytic activity and reinforced its structural stability. Comprehensive characterisation was performed using PXRD, FT-IR, SEM-EDS, XPS, and N₂ adsorption-desorption isotherms. Scavenger tests confirmed that hydroxyl (˙OH) and superoxide (˙O₂⁻) radicals played a crucial role in the photocatalysis. The material demonstrated excellent reusability, maintaining high performance over three cycles with minimal structural changes. Furthermore, a toxicological evaluation of the degradation by-products was conducted using
