Photo catalytic degradation of dye work was studied using ZnO nano particles under UV irradiation. Chemical precipitation method was used for synthesis of zinc oxide and characterization studies were done by XR-diffraction technique (XRD), scanning electron micro scope (SEM) and band gap was determined using UV-visible spectrophotometer. Studies were conducted varying the photo catalyst, methylene blue concentration and residual concentration of methylene was monitored using spectrophotometer. The products were found by high performance liquid chromatography (HPLC). The peak photo degradation of methylene blue at concentration [0.75x10-5] M was observed with dosage of 0.05g/100ml. In addition reusability aspects of nano particles where also studied which revalue’s that reused nano particles exhibited same results as that of virgin particles.
