The organic pollutants are polluting the drinking water so, it is a fi eld of great interest to clean this water by using somesophisticated materials. For this purpose, the nanostructured materials are playing vital role to attain sustainable and puredrinking water by degrading organic pollutants. The synthesis of such photocatalytic material without using harmful chemicals,is one of the important existing challenges. Thus, to tackle this challenge, we have prepared green synthesized Sn-dopedWO 3 nanomaterials by varying the content of Sn from 2 to 6 wt% and assisting from moringa oleifera seeds’ extract. Thecrystal structure, morphology, optical and photoluminescence properties of as prepared samples were investigated throughx-ray diff raction (XRD), scanning electron microscopy (SEM), ultraviolet visible spectroscopy (UV-vis) and photoluminescencespectroscopy (PL) techniques. Among of as prepared samples, the 4Sn-WO 3 (4 wt% Sn doped WO 3 ) sample hasexhibited the reduced optical band gap value i.e. 2.80 eV than 3.02 eV for pure WO 3 sample. This optimized sample has alsoshown the lowest e-h recombination rate. To test the photocatalytic performance, the methylene blue was used as a modeldye. Out of all samples, 4Sn-WO 3 sample has shown 95% degradation activity against this water pollutant. These fi ndingsspecify that the as mentioned novel photocatalytic nanomaterial will provide a signifi cant advancement in the environmentalfi eld to degrade the organic pollutants.
