Photocatalytic degradation is a hopeful approach for decay of dyes. Photocatalytic degradation of phenolic compounds such as methylene blue has been studied using different concentration in the range of (0.1-2) wt. % from Copper oxide CuO nano-particles. Nano-particles have been synthesized employ Sol-gel technique which is considered as a chemical engineering technicality for formations of an oxides network during polycondensation reactions of a precursor molecule in a solution. This study was carried out under special and natural conditions with and without UV source. The nanoparticles had been characterized using various techniques. The first one was X-Ray Diffraction (XRD), which shows that the structure of CuO nanoparticles are monoclinic of CuO nanoparticles, the normal crystal size of copper oxide NPs was found to be equal to 13nm. The second characterization techniques was SEM (Scanning Electron Microscopy), The SEM micrographs of prepared samples show the distribution particles and the morphology of copper oxide NPs (with size of particle~13nm). Catalysts were performed via UV– Visible spectrophotometer. The rate of degradation for methylene blue was monitored spectro-photometrically by measuring absorbance of dye. The effect of dye concentration and catalyst concentration were studied.
