The synergistic effect between bimetallic catalysts has been confirmed as an effective method for activating persulfate (PMS). Therefore, we immobilized copper–cobalt on chitosan to prepare bimetallic carbon catalysts for PMS activation and degradation of reactive dyes. Experimental results demonstrate that the CuCo-CTs/PMS catalytic degradation system exhibits excellent degradation performance toward various types of reactive dyes (e.g., Ethyl violet, Chlortalidone, and Di chlorotriazine), with degradation rates reaching 90% within 30 min. CuCo-CTs exhibit high catalytic activity over a wide pH range of 3–11 at room temperature and under static conditions, degrading over 92% of RV5 within 60 min. ultraviolet–visible (UV–vis) spectroscopy and color changes in the dye solution confirm the effective degradation of RV5, with a degradation rate of 97.2% within 10 min. Additionally, CuCo-CTs demonstrate good stability and reusability, maintaining a degradation rate of 92.8% after eight cycles. Kinetic studies indicate that the degradation follows pseudo-first-order kinetics. Furthermore, based on the results of radical scavenging experiments, the catalytic degradation mechanism of the dye involves both radical and nonradical pathways, with 1O2 identified as the primary active species. This study provides insights and experimental evidence for the application of persulfate oxidation in the treatment of dyeing wastewater.

In this study, manganese selenide/copper oxide nanocomposites anchored on multi-walled carbon nanotubes (MnSe/CuO/MWCNTs) were fabricated with different ratios and their characteristic properties were evaluated. Microscopic images show the decoration of CuO on MnSe without changing morphology. UV–Vis analysis indicates that the best optical properties of MnSe/CuO/MWCNT nanomaterials via 2.06 eV as a band gap energy. The photocatalytic ability of the fabricated nanomaterials was evaluated by the decomposition of rhodamine B (RhB) (97.23%) and malachite green (MG) (100.0%) under visible LED irradiation within 45 min. Furthermore, the antibacterial activity of the prepared nanosamples was investigated against Escherichia coli and Staphylococcus aureus strains. The results show that MnSe/CuO/MWCNTs can be used as a stronger antibacterial agent.
