In this study, CuO-CoOx/SBA-15 catalysts were successfully synthesized via ultrasonic impregnation, and their performance in degrading nitrobenzene within a Fenton-like system was investigated. The catalyst materials characterized using X-ray diffraction (XRD), photoelectron spectroscopy (XPS), inductively coupled plasma mass spectrometry (ICP-MS), scanning electron microscopy (SEM), transmission microscope(TEM) energy-dispersive (EDS). featured well-distributed CuO-CoOx nanoparticles the mesoporous SBA-15 support. Compared to CuO/SBA-15 Co3O4/SBA-15 with similar microstructures, exhibited Cu-Co dual active centers higher abundance of redox-active sites. During catalytic degradation, H2O2 continuously activated on surface through efficient Cu+/Cu2+ Co2+/Co3+ redox cycles. experimental conditions (initial pH, dosage, dosage) optimized, resulting 99% removal over wide pH range (3.0-9.0). primary mechanisms for oxidation subsequent CuO-CoOx/SBA-15-H2O2 identified as reactions hydroxyl radicals (·OH).
