This report presents the outcomes of exerting extracted Salvadora persica for synthesizing ZnO nanoparticles (ZnO−NP) and Mn‐doped ZnO nanorods (Mn−ZnO−NRs) through a viable and economical “green” route. The products characteristics were configured by the means of X‐ray diffraction (XRD), field emission scanning electron microscopy (FESEM), energy‐dispersive X‐ray (EDX) spectroscopy, UV‐visible spectroscopy (UV‐Vis) and Raman assessing technics. As the constructional evaluations approved the progress of well crystalline nano, the EDX analyses approved the doping of Mn, which interestingly succeeded in significantly altering the spherical framework of ZnO into a rod‐looking structure. The following steps involved the employment of MTT trial to assay the cytotoxic impacts of our sample towards breast (MCF‐7: Michigan Cancer Foundation‐7) cancer cell line, resulting in confirming the superior outcomes of Mn−ZnO−NRs than the solitary case of ZnO. The boosted functionality of the doped product may be attributable to the appearance of Mn into the lattice of ZnO. In addition, the evolved morphology of ZnO, obtained through the doping process, could have caused substantial developments in the cytotoxic operation of doped sample as well.

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.
