Abstract:
A good approach for the photo degradation of Methylene Blue (MB) dye under UV Visible irradiation is the use of Ag doped nickel oxide –zirconium oxide core shell
nanoparticles as a photocatalyst that showed the high photocatalytic activity, highly
magnetic separability and cost-effective results. The nanoparticles of Ag doped nickel
oxide-zirconium oxide (Ag, NiO/ZrO2, x=1%, 3%) were prepared by using hydrothermal
synthesis route. The structural and morphological properties of synthesized nanoparticles
studied by X-ray diffraction (XRD), scanning electron microscope (SEM), Fourier
transform infrared spectroscopy (FTIR), Energy dispersive spectroscopy (EDX), UV visible spectroscopy, and Photoluminescence (PL). The structural morphology showed
that prepared samples are uniform.The structural properties confirmed to be in good
agreement for both XRD, and SEM results and confirmed the cubical nature of the
prepared spinel. Furthermore, the increase in size of the nanoparticles with increase in
Sliver (Ag) contents, confirmed from the diffraction peaks and SEM analysis. The size of
crystallites ranged in 29.13nm evaluated by using Debye-Sharer‘s formula from more
intense diffraction peak. The compositionof the prepared specimen confirmed by Fourier
transform infrared spectroscopy (FTIR).Photocatalysis carried out to check the
photocatalytic activity of the synthesized nanoparticles having different concentrations of
, for the degradation of Methylene Blue (MB) dye under UV-Visible light. The
photocatalytic activity checked, resulted 8%, 27%, 41% and 80% for Sliver doped nickel zirconium oxide respectively, for the degradation of Methylene Blue (MB) dye under
UV-Visible irradiation in 0 ,30 ,60, 90 and 120mins, it is concluded that the
photocatalytic activity increased by increasing reaction time and the concentration of
Sliver , and this can be increased up to 80 %. The prepared core shell nanoparticles
attested to be cost effective, ecofriendly, reusable after recycling, high magnetic
x
separability after use, and high photocatalytic activity for the photodegradation of
Methylene Blue (MB) dye under UV-Visible irradiation.
