Biosynthesis of Zinc Oxide Nanoparticles by Prunus scoparia leaf extract and Assessment of their Antioxidant and Catalytic Activity

In recent years, nanoscience has been widely applied in many fields, such as chemistry, physics, electricity, and agriculture. Nanoparticle preparation must be carried out using non-toxic, inexpensive, and safe chemicals in order to advance this science. Thus, following the principles of green chemistry, we synthesized high-value zinc oxide nanoparticles using almond (Prunus scoparia) leaf extract. UV-Vis and FT-IR spectroscopy as well as XRD and SEM were used to characterize the properties of the nanoparticles synthesized from the leaf extract. During the UV-Vis analysis, the synthesized nanoparticles were found to have their special peak at ۳۹۸ nanometers. FT-IR spectroscopy as well showed a distinct peak of Zn-O stretching vibration positioned at ۵۰۴.۳۸ cm-۱. According to the XRD test, these nanoparticles synthesized from a biogenic source are hexagonal wurtzite with an average grain size of ۷۱.۳ nm. Using SEM analysis, the shape and size were found to be spherical and within the range of ۶۷-۱۰۳ nanometers. The biosynthesized ZnO nanoparticles degraded Methylene blue as organic dye in ۲۰ minutes using NaBH۴ in a facile and uncomplicated reaction. In addition, antioxidant activity of these nanoparticles was studied through DPPH radical scavenging method, which proved that the synthesized nanoparticles are potent radical scavenger. Eventually, our findings in this study prove the reduction and stabilization properties of almond leaf extract and show that the obtained nanoparticles are a strong catalyst.
