Abstract

In this article we synthesized ZrO₂/ZnO composite nanoparticles doped Ce⁴⁺ ions by hydrothermal method. Photocatalytic activity of methylene blue (MB), under simulated sunlight was tested. Analysis of X-ray diffraction (XRD) has been shown ZnO/ZrO₂ doped Ce⁴⁺ nanomaterials exist in the form of composites and purity. Scanning electron microscope (SEM), Fourier-transform infrared spectroscopy (FT-IR) have also been studied. The results show that the morphology of synthetic composite nanomaterials is nanoparticles with diameter of 40 nm. When meterial was doped Ce⁴⁺, the perfomance degradation of MB is 73.13%, higher than that of no doped Ce⁴⁺ ion with 44.73%. This first result shows that the ZrO₂/ZnO nanocomposites doped Ce⁴⁺ have potential applications in water pollution treatment.
