Synopsis

In the present work zinc oxide nanoparticles (ZnO) were successfully synthesized by a sol-gel method (ammonia as precursor) and Zinc chloride solution neutralizing with ammonia to pH values of 7,conventional heating and washed with water &Ethanol to get Zinc oxide nanoparticles. The ZnO powder obtained from this method is calcined at 800oC and 900oC temperatures. The GO was prepared by using Hummers method. The ZnO+GO were prepared by adding ZnO with different concentrations of GO using heterogeneous photo catalytic degradation of methylene blue for removal of pollutants. The samples were characterized by X-ray diffraction (XRD), Scanning Electron Microscopy (SEM), Transmission electron microscopy (TEM), UV- visible spectroscopy. Results show that the calcinations temperature significantly affected the crystalline nature, particle size, and optical properties of the processed ZnO nanoparticles. The XRD spectra indicate that the ZnO crystal has a hexagonal wurtzite structure. TEM images agreement with the XRD data shown that the average size of the nanoparticles. The optical properties of the samples are investigated by measuring the UV-VIS absorption at room temperature.
