Heterogeneous Fenton-like CuO-CoO_x/SBA-15 catalyst for organic pollutant degradation: synthesis, performance, and mechanism.

ABSTRACT: In this study, CuO-CoO_x/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 were characterized using X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS), inductively coupled plasma mass spectrometry (ICP-MS), scanning electron microscopy (SEM), transmission electron microscope(TEM) and energy-dispersive X-ray spectroscopy (EDS). The CuO-CoO_x/SBA-15 catalysts featured well-distributed CuO-CoO_x nanoparticles within the mesoporous SBA-15 support. Compared to CuO/SBA-15 and Co₃O₄/SBA-15 catalysts with similar microstructures, the CuO-CoO_x/SBA-15 catalysts exhibited Cu-Co dual ac
