Developing nations need to propel their financial development by expanded modern action because of their expansion in populace. Such businesses are the major reason for water contamination. Ventures, for example, the textile industry produce organic dyes and these dyes can never again be expelled by biodegradable methods without trouble. Such dyes can be poisonous to oceanic creatures, plants and the human body. Zr doped ZnO nanoparticles are set up by the sol-gel method with post-annealing. thin films of Zr-doped ZnO, with Zr concentrations fluctuating from 0 to 5 at, have been readied utilizing a sol-gel method. Crystallinity, microstructure, and optical properties influenced by Zr concentration were explored. Doped ZnO with Zr has been gotten by sol-gel method and portrayed by powder X-ray diffraction, energy dispersive X-ray spectrum, Scanning electron micrographs, and UV– visible diffuse reflectance and photoluminescence spectroscopy. Powder XRD demonstrates that synthesized Zr doped ZnO has hexagonal wurtzite structure and high crystallinity, DRS uncovers that wavelength are shifted from UV district to visible locale when Zr doping. PL spectra obviously uncover that the recombinations of electron-hole pair in ZnO are stifled by Zr doping. Zr-doping improves the photocatalytic debasement of methylene blue dye than ZnO under visible light. The impact of Zr substance on the structure, morphology, absorption, emission, and photocatalytic action of ZnO SNPs was examined efficiently.
