“…The integration of Zn ions to the lattice of CeO 2 seemed to reduce the band gap of CeO 2 by producing levels of impurity below the CB in the band gap, which consequently leads to the transferring of electrons from the VB towards the mentioned energy levels. Once the shifted electrons to the surface are adsorbed by O 2 and cause the formation of O 2 ions, they go through another conversion step and create strong redox species, known as OH ions, to function as the degrading agent of perilous AO7 that is adsorbed on the surface 45,46 …”

The presented paper introduces a green route for the arrangement of pure and 1%, 2%, and 4% zinc doped cerium oxide nanoparticles (Zn-doped CeO 2 NPs) by involving the extract of Salvadora persica. The analytical results of powder X-ray diffraction (PXRD), ultraviolet-visible (UV-Vis), field emission scanning electron microscopy (FESEM), energy dispersive X-ray (EDX), and Raman techniques confirmed the successful synthesis of NPs. According to PXRD outcomes, pure CeO 2 NPs have a cubic phase. Moreover, as a result of the zinc doping within the crystal framework of this material, a noticeable alteration was observed in the placement of CeO 2 (101) peak. The size of pure CeO 2 NPs was measured by the FESEM analysis to be around 20-25 nm, which was decreased with the doping of zinc into CeO 2 structure. According to the UV-Vis outcomes, appeared peak in 343 cm À1 confirmed the formation of CeO 2 NPs; and this peak shifted by the doping of zinc. The observed Raman active band F 2g at 459 cm À1 in the graph of CeO 2 can be related to the fluorite type of CeO 2 construction. Moreover, we evaluated the photocatalytic functionality of the prepared samples towards acid orange 7 (AO7) dye at visible light. The gathered data indicated 2% Zn-doped CeO 2 as the optimum sample due to eliminating 83% of AO7 dye at the volume of 15 mg L À1 in pH = 7. Therefore, performing a doping process on these NPs was a suitable choice for improving the photocatalytic activity of CeO 2 on AO7 dye.
