In this study, magnetic nanocomposites based on reduced graphene oxide (rGO) were synthesized and their photocatalytic activities were investigated. rGO–Fe3O4 nanostructures were synthesized by the solvothermal method and copper oxide (CuO) nanoparticles were deposited on the surface at different ratios by the co-precipitation method. Binary and ternary nanocomposites with different component ratios (rGO–Fe3O4, rGO–Fe3O4–CuO (1:8:0.5, 1:8:1, and 1:8:2)) were characterized by XRD (X-Ray Diffraction), SEM (Scanning Electron Microscope), TEM (Transmission Electron Microscope), UV–Vis (UV–visible Spectrophotometer), and FTIR (Fourier Transform Infrared Spectroscopy). Photocatalytic activity of the prepared nanocomposites was observed with methylene blue (MB) dye under visible LED light. The results showed that the synthesized nanocomposites had photocatalytic efficiencies ranging from 36% to 89% depending on the component ratio. The rational incorporation of CuO into rGO–Fe3O4 significantly improved photocatalytic efficiency and demonstrated a stable Z-scheme heterostructure, highlighting the potential of this ternary composite for efficient and scalable wastewater treatment.
