Abstract

The present study focused on microwave assisted synthesis of zirconium nanoparticles (ZrO₂NPs) using leaf extract of Phyllanthus niruri as ecofriendly approach and assessed its antimicrobial and bioremediation efficiency. Visual color transition from yellow to brown indicates the formation of ZrO₂NPs which was further substantiated by UV-Visible absorption peak at 300 nm. Dynamic Light Scattering (DLS) analysis revealed that the average particle size of ZrO₂NPs as 121.5 nm with negative zeta potential of -22.6 mv. Scanning electron microscopic analysis showed spherical shaped nanoparticles with an average size of 125.4 nm. Results of photocatalytic studies revealed that ZrO₂NPs exhibited 74%, 62% and 57%, dye degradation for methyl red, methyl orange, and methyl blue respectively. Antimicrobial studies depicted that ZrO₂NPs exhibited bactericidal activity against Bacillus subtilis, Staphylococcus aureus, Escherichia coli, Klebsiella pneumoniae, and Aspergillus niger at dose of 200 μg/mL. Overall results of the present study revealed biogenic synthesis of ZrO₂ NPs with potent bioremediation and antimicrobial properties.
