AN ENHANCED PHOTOCATALYTIC PERFORMANCE BASED ON MoO3 AND Zn DOPED MoO3 NANO STRUCTURES

The MoO3 and transition metal of (Zn) doped MoO3 nanostructures were synthesized by simple wet chemical method. In this article, we used for the high efficient Zn x (x = 5, 10 &15%) for nanophotocatalyst in visible region. The process is simple, cost-effective and can be easily scaled-up. It is shown that the catalytic behavior of MoO3 and Zn doped MoO3 that are synthesized in this method has good efficiency for degradation. The MoO3 and Zn/MoO3 photocatalysts are characterized by X-ray diffraction (XRD), Field emission scanning electron microscopy (FE-SEM) and Scanning Energy Dispersive X-ray spectroscopy (EDS).Fourier Transform Infrared Spectroscopy (FTIR) and Raman spectroscopy. The obtained results of XRD and FE-SEM are confirmed the well dispersion of Zn nanoparticles and highly well improvement of the regular Zn nanoparticles on the surface of MoO3 nanostructures. The chemical nature of the bonding confirmation details about the Zn doped MoO3 is analyzed through vibrational spectra of FTIR. The enhanced photocatalytic activities of Zn doped MoO3 nanostrucutre are attributed to the degradation efficiency under UV-visible light irradiation inorganic segment. Also, evaluation of the photocatalytic degradation of Methyleneblue(MB) was done under UV-visible light irradiation. The results are showed that these structures exhibit promising candidates to degrade methylene blue (MB). Based on the characterization, it is found that Zn doped MoO3 structure showed higher photocatalytic activity than MoO3. This relatively high photocatalytic activity may be attributed to the charge transfer between those bi-layered oxides. Besides, the kinetic studies revealed that the photocatalytic oxidation kinetic theory follows a pseudo-first-order reaction. Finally, the stability, cyclic efficiencyand growth mechanisim of the Zn doped MoO3 photocatalyst are investigated.
