Green Synthesis and characterization of Lead Oxide Nanoparticles using Piper Betle leaf

Abstract

Lead oxide nanoparticles were synthesized by using cost effective and eco friendly green method assisted by piper betle leaf extract. The UV absorption spectrophotometer analysis of leaf extract and metal compounds showed absorbance spectra in the range 300-400 nm. The UV-Vis spectroscopy shows Surface Plasmon resonance of PbO nanoparticles at 320 nm indicating that the particles are poly dispersed. The FT-IR measurements were carried out to identify the formation of lead oxide nanoparticles and possible molecules such as OH, C=C, C=O and aromatic compounds. The FT-IR analysis played a pivoted role in displaying the nanoparticles which showed strong absorbance in the range 518-600 cm-1 for lead oxide nanoparticles. The diffraction peaks and planes of ions are indexed. From the ‘X’ ray diffraction analysis, the size of the lead oxide nanoparticles is 70 nm as calculated by Debye scherrer’s equation. The size, shape and structure of nanoparticles were also analyzed by Scanning electron microscope showing tetragonal shape of nanoparticles aggregation. This green synthesis method has many advantages over the chemical method because it reduces the use of toxic metals in the synthesis process.
