Abstract

Water pollution due to organic pigments from factories is a cause for concern. Treatment methods such as adsorption, flocculation, or filtration, often consume energy and cause secondary pollution. Photocatalytic methods are currently of interest to scientists. Especially photocatalysts use solar energy. Because this is a clean, endless source of energy. In this paper, we synthesisized ZrO2/ZnO and ZrO2/CuO composite nanoparticles doped with Ce4+ ions by hydrothermal method. Photocatalytic activity of methylene blue (MB), under simulated sunlight was tested. The results show that the morphology of synthetic composite nanomaterials is nanoparticles with diameter of 60-100 nm. When meterial was doped with Ce4+, the perfomance degradation of MB is 73.1% in 180 minutes, higher than that of no doped Ce4+ ion with 44.1%. Analysis of X-ray diffraction (XRD), scanning electron microscope (SEM), Fourier-transform infrared spectroscopy (FT-IR) have also been studied. This result shows that the ZrO2/ZnO and ZrO2/CuO nanocomposites doped with Ce4+ have potential applications in water treatment and environmental pollution.
