The increasing requirements for paints and chemicals in industry have necessitated the use of several techniques to reduce pollution, including a combined chemical precipitation(Co-precipitate) approach to prepare NiO nanoparticles in the form of NPs nanoparticles, where structural and morphological analyzes revealed the formation of nanostructures, such as the scattering of X-rays (XRD) , Fourier transform Infrared spectroscopy(FTIR) a technique used to analyze the interaction between matter and infrared radiation by measuring the absorption, emission, or reflection of infrared light, and dispersive energy X-ray spectroscopy (EDX) analytical techniques used in scientific research, , Electron scanning microscopy ,and Thermal gravimetric analysis (TGA). The second part includes the study of the photo catalytic activity of prepared nanocomposite, using a fast green dye. The rate of the photocatalytic degradation process was affected by different parameters such as the concentration of dye, effect of a mass of catalyst, and the effect of temperature. The experiments were performed under optimum conditions from (0.15 g / 100 mL) of NiO nanocomposite, with an air Rate of flow of 10 mL/min. The best removal amount of Fast green dye was (91.45%). The effect of dye concentration has been used to study the optimum value of Fast green dye (10mg/L) dye. The activation energy for the photo degradation process calculated using the Arrhenius equation was equal to (31.67. ±1 kJ.mol-1).
