Zinc Vanadium Oxide Nanoparticles were synthesized by varying temperature through solution combustion method using zinc nitrate and ammonium meta vanadate as raw materials and urea as fuel. For the photocatalytic degradation of methylene blue dye due to its high toxicity effect in water resources. Most of the chemicals involved in the preparation of methylene blue dye produces toxic gases after their use in the industries. The potential of Zinc Vanadium Oxide which acts as photo catalyst was investigated by degrading methylene blue dye by photocatalytic activity. To degrade such harmful chemicals released in the water resources Zinc Vanadium Oxide nanoparticles plays a crucial role on photocatalytic degradation process. In this study, we discussed about the Zinc Vanadium Oxide nanoparticles on photocatalytic degradation of methylene blue dye. The thermally treated material subjected to PXRD (Powder X-ray diffraction) studies confirms monoclinic structure which corresponds to the plane miller indices with (1,1,0), (2,2,0), (1,1,1) and (3,1,1) respectively according to JCPDS NO: 74- 1262. The grain size of zinc vanadium oxide nano powder is calculated by using Debye-Scherrer’s formula calculated to be average crystallite size is 21.3nm. The band gap of the sample determined by Diffusion reflectance spectra by plotting Kubelka Munk function versus energy. Eg is found to be 2.38eV. The FTIR spectrum of Zinc Vanadium Oxide Nanoparticles was found to consists of characteristic absorption peaks. It is well known demonstrated for the high level application for the degradation of organic pollutants under visible radiation. The degradation of methylene blue dye was performed at different conditions of variables like catalyst dose, reaction time and dye initial concentration shows a valuable effect on dye degradation under UV light radiation. The photocatalytic degradation of methylene blue dye is studied under UV-visible light. The zinc vanadium oxide photocatalyst it clearly shows that breaking of the dye bonds.
