Sulfamethoxazole (SMX) is a widely used antibiotic for bacterial infections and frequently found in surface waters wastewater treatment plant effluents, where it commonly co-administered with trimethoprim. Because of its emerging ecological health risks, the development effective elimination strategies urgently required. In this study, rapid microwave-assisted technique was employed to synthesize Pd/g-C3N4 photocatalyst SMX aqueous solution. The structure optical properties all samples were characterized using X-ray diffraction (XRD), transmission electron microscopy (TEM), photoluminescence (PL), UV–visible diffuse reflectance spectroscopy. photocatalytic performance systematically evaluated under visible-light irradiation. results demonstrated that achieved 97% removal efficiency, significantly outperforming pure g-C3N4, which reached only 57% removal. degradation rate constant calculated be 0.0139 min−1, approximately 6.6 times higher than bare g-C3N4. This enhanced attributed incorporation Pd nanoparticles, effectively suppressed recombination photogenerated electron–hole pairs promoted charge separation. influence key operational parameters, including pH, concentration, catalyst dose, examined. Furthermore, mechanism explored elucidate pathways.
