Biosynthesis, Characterization and Antibacterial Efficaciousness of Zirconium Oxide Nanoparticles Using Azadirachta Indica Extract

Abstract

Zirconium oxide (ZrO₂) nanoparticles were synthesized by biosynthesis technique using Azadirachta indica leaf extract. The synthesized ZrO₂ nanoparticles were subjected to X-ray diffractometer, Ultraviolet-visible spectroscopy, FTIR spectrophotometer, Field emission scanning electron microscopy and energy dispersive X-Ray spectrometer. The particle size, micro strain, dislocation density and the orthorhombic phase of prepared ZrO₂ nanoparticles were determined via XRD.  Bandgap value of the ZrO₂ nanoparticles was found to be around 5.4 eV, using UV-visible spectroscopy. From FTIR, the functional groups were identified. FESEM results show a uniform distribution of the ZrO₂ nanoparticles. Zr and O elements in the synthesized samples are conformed by EDX. The synthesized ZrO₂ nanoparticles antibacterial efficacy to inhibit Escherichia coli, Pseudomonas aeruginosa, Enterococcus faecalis and Streptococcus mutans was investigated
