Synthesis of Plant Mediated ZnO Nanoparticles of Tribulus terrestris Extract and Optical, Functional, Structural, Morphological, Microbial, and Dielectric Analysis

ABSTRACTIn current trends, the green synthesis of metal oxide nanoparticles acts as an eco‐friendly and biocompatible methods. In this present study, we use the aqueous extract of Tribulus terrestris to prepare the zinc oxide (ZnO) nanoparticles along with the supports of acetate dihydrate. The chemical constituents in the plant extract of T. terrestris act as both reducing and controlling agents for producing the ZnO nanoparticles. Initially, the formation of ZnO nanoparticles was identified through the characteristic peak that appeared at 372 nm in the UV–Vis spectrum. In SEM analysis, the nanoparticles' morphology was revealed as needle‐like distributions. The Fullprof‐assisted Rietveld refinement executed on the measured PXRD pattern has confirmed the hexagonal crystalline nature of the biosynthesized ZnO nanoparticles. FTIR spectroscopy technique was used to identify the functional groups responsible for the formation of ZnO nanoparticles. In the FTIR spectrum, the appearance of fingerprint region observed at 472 cm−1 represents the presence of ZnO nanoparticles. Using energy dispersive X‐ray (EDX) analysis, we identified the chemical compositions of synthesized crystalline powdered form of nanoparticles with their weight percentage. In addition, the antibacterial activity and dielectric behavior of the synthesized ZnO nanoparticles have been investigated. Finally, the utilization of biodegradable nanocomposite materials will provide a novel path for their outstanding electronic applications and storage devices.
