The WO3-TiO2 novel nanomaterial was synthesized by precipitation method and sonication technique. The nanomaterial for the degradation of malachite green (MAG) dye under natural sun light irradiation. The synthesized nanomaterial is characterized by HR-SEM with EDX, PL and UV-Vis DRS analysis. The photodegradation of MAG at various parameters are reported. The mechanisms of dye degradation in natural sun light explain the higher photocatalytic activity of the catalyst. The result indicates the advantage of wastewater treatment by it. The electrochemical study from DSSC analysis showed increased current by WO3-TiO2 nanomaterial. It was proposed that the catalyst was found to be stable and reusable.
