Summary: In this study, the WO3-CuO/RGO nanocomposite was successfully fabricated for visible-light activated degradation of organic pollutants using persulfate (PS). The characterization results confirmed the successful construction of the nanocomposite. The effects of various operating factors on the removal process were investigated. Under optimal conditions, complete degradation of diazinon and rhodamine B was achieved. Free radicals, including singlet oxygen (1O2), hydroxyl radical (OH center dot) and sulfate radical (SO4 center dot-), played important roles in the degradation process. The WO3-CuO/RGO-PS system showed promising potential for efficient removal of organic pollutants due to its high catalytic activity and recyclability.

Summary: In this study, cobalt sulfides (Co9S8) coated on the nitrogen and sulfur co-doped graphene (Co9S8@S-N-RG) were prepared and used for the degradation of antibiotic sulfamethoxazole (SMX). The Co9S8@S-N-RG showed superior catalytic activity, degrading SMX with a mineralization efficiency of 38.7% within 20 minutes. The activation of peroxymonosulfate (PMS) by Co9S8@S-N-RG was attributed to the production of sulfate radicals, with the participation of Co2+ and sulfur species. Carbon defects, CO, pyridinic N, and pyrrolic N also played a role in PMS activation. This study provides insights into the PMS activation mechanism and offers a stable PMS activator.
