The environmentally friendly synthesis of GO-TiO₂/Fe₂O₃ nanocomposites were synthesized using Moringa oleifera seed extract as a reducing agent. GO (graphene oxide) was prepared with the Hummer’s method and TiO₂ and Fe₂O₃ were co-doped onto the graphene surface through ultrasonication. Structural characteristics were determined via X-ray diffraction (XRD), surface morphology analyzed with field emission scanning electron microscopy (FESEM) and High-Resolution Transmission Electron Microscopy (HRTEM), and vibrational modes identified using Raman spectroscopy. Optical properties were assessed using UV–VIS and Photoluminescence techniques, while the presence of elements was confirmed with Fourier Transform Infrared Spectroscopy (FTIR) and energy dispersive spectroscopy (EDS). Porosity and surface area were determined through nitrogen adsorption and desorption via BET studies. The NC Fe3 nanocomposite featured a crystalline size of 20 nm, a high surface area of 75 m²/g, a 2.75 eV bandgap energy, and an 8.6 nm particle size distribution. The d-spacing values from HRTEM and XRD analyses matched. Notably, under UV light for 90 min, the photocatalytic degradation of methylene blue (MB) reached 85%, exhibiting pseudo-first-order kinetics with a rate constant of 0.009 min⁻¹ and a correlation coefficient of 0.9853. Similarly, the photocatalytic degradation of Carbol Fuchsin (CF) achieved 90% under UV light for 90 min, with pseudo-first-order kinetics characterized by a rate constant of 0.01064365 min⁻¹ and a correlation coefficient of 0.9923.
