In this study, we developed novel BiOBr/WO2.72 nanocomposites (abbreviated as BO/WO) and systematically investigated their photocatalytic degradation performance against the pesticide dichlorvos under visible light irradiation. The experimental results demonstrated that BO/WO achieved an 85.4% of within 80 min. comparison, BO alone a degree 66.8%, WO 64.7%. Furthermore, retained 96% initial activity over five consecutive cycles, demonstrating exceptional stability. Advanced characterization techniques, such high-resolution transmission electron microscopy (HRTEM), X-ray photoelectron spectroscopy (XPS), paramagnetic resonance (EPR) confirmed composition catalytic mechanism composite material. findings indicated nanocomposites, through optimized Type-I heterojunction structure, efficient separation transport photogenerated electron–hole pairs, significantly enhancing organophosphate pesticides. This research not only propels development high-performance materials, but also provides innovative strategies robust scientific foundation for mitigating global pollution, underscoring its substantial potential environmental remediation.
