In the present, nanocomposite with high photocatalytic degradation used in the removal pollutant. preparation by hydrothermal method was first used ZnO nanoparticles, and then a ZnO/WO3 nanocomposite. Band gap energy (BG), X-ray diffraction (XRD), energy dispersive X-ray spectroscopy (EDX), field emission scanning electron microscopy (FE-SEM), and Fourier transform infrared spectra (FT-IR) were used to describe the products. The presence of WO3, ZnO, and ZnO-WO3 is indicated by the crystalline ZnO nanoparticle peaks at 32 o, 34 o, and 36 o and the WO3-ZnO nanoparticle peaks at 26 o, 27 o, 28 o, and 33 o. The band gap obtained from extrapolating this data after doping WO3 onto ZnO nanoparticle is 2.81 eV, highlighting the possibility of WO3-ZnO to be utilized in solar cell-based systems in the future in addition to their promise as efficient photo catalysts. This work opens new sight in the synthesis and characterization of semiconducting nanomaterials for optical application.
