Phytochemical-Mediated Synthesis of Nanozinc Oxide Particles and Its Antibacterial, Photocatalytic Degradation of Methylene Blue

Abstract

Using aqueous leaf extract of Givotia moluccana, we offer a bioreduction technique for phytochemical-mediated production of nanozinc oxide (N-ZnOPs) particles. Phytochemicals such as polyphenols, flavonoids, and proteins were discovered in the water extract. UV–visible spectroscopy (UV-Vis), Fourier transform infrared spectroscopy (FT-IR), X-ray diffraction (X-RD), and transmission electron microscopy (TEM) are as follows. The UV–visible spectra of synthesized N-ZnOPs revealed absorption peaks at 370 nm. The crystalline nature of ZnO was confirmed by X-RD pattern analyses. Furthermore, TEM pictures demonstrate the creation of hexagonal-shaped N-ZnOPs with diameters ranging from 20 to 50 nm, which is also confirmed by the particle size analyzer, DLS. The synthesized N-ZnOPs displayed antibacterial action as well as photocatalytic destruction of methylene blue (MB) dye, in contrast to gram +ve and gram–ve bacteria. Using the biosynthesis pathway, the current study presents a simple, ecofriendly, and uncomplicated route for the creation of N-ZnOPs. N-ZnOPs are utilized in rubber, paint, coating, and cosmetics. N-ZnOPs are attractive in biological applications due to their biocompatibility, cost, and low toxicity.
