This research work reports the synthesis of novel MoS 2 /MnO 2 /WO 3 ternary composites using Azadirachta indica extract. These nanomaterials were characterized by X-ray diffraction, photoluminescence spectra, FT-IR spectrum, ultraviolet–visible diffused reflectance spectroscopy, scanning electron microscopy and EDX to evaluate various properties. The UV-DRS spectroscopy confirmed the bandgap tuning whereas XRD confirmed the optimization in crystallinity and the average crystallite size. Interestingly, PL analysis reveals the fact that the charges recombination rate of ternary composite was much lower than that of the pure materials, hence, validating the extra exciting time for charge carriers which will be beneficial for photocatalytic removal of harmful products. BET analysis confirmed the enhancement in specific surface are that is favorable for the photocatalytic reactions. The synthesized photocatalysts were tested to eliminate harmful effluents in MB dye and Naproxen Sodium analgesic. The MoS 2 /MnO 2 /WO 3 , (46.5 nm average particle size, 2.28 eV bandgap energy), has shown 94.97 % and 85.25 % photocatalytic efficiency for removal of harmful effluents MB dye and Naproxen Sodium analgesic in 120 min. This work demonstrates the synergistic effect of MnO 2 and WO 3 nanostructures which could be a best choice for enhancement of photocatalytic efficiency for MoS 2 based novel materials.
