ZnMoO4 Nanoparticles: Novel and Facile Synthesis, Characterization, and Photocatalytic Performance

In this research, ZnMoO4 nanoparticles was synthesized through novel and fast chemical method. The products were prepared under different irradiation time and power. The shape, size, and crystalline structure have been investigated through Scanning Electron Microscopy (SEM), Transmission Electron Microscopy (TEM), and X-ray diffraction (XRD) analysis respectively. The optical properties of samples were prepared via UV-Vis analysis. Results confirmed that shape and size of ZnMoO4 nanoparticles could be changed under different synthesis condition. The obtained results from optical properties of prepared ZnMoO4 nanoparticles approved that the prepared nanoparticles have high potential for the photodegradation of organic pollutants. Methylene blue and rhodamine B were applied for investigation phtocatalytic properties of ZnMoO4 nanoparticles. Results showed that methylene blue and rhodamine B were photodegraded under UV irradiation after 90 minutes 92.6% and 82.4% respectively. This excellent performance was due to the suitable band structure of synthesized ZnMoO4 nanoparticles which led to prevention recombination of photo-generated electrons and holes. This work introduces ZnMoO4 nanoparticles as an attractive photocatalyst for removal of organic pollutants from water.
