Green Synthesis of Selenium Doped Zinc Oxide Nanoparticles using Mangifera indica Leaf Extract and Its Photodegradation and Antibacterial Activities

Abstract

Biomolecule-mediated nanoparticle synthesis has recently gained the attention of researchers due to its eco-friendly and non-toxic nature. Herein, we aimed to describe the rapid green synthesis of selenium doped zinc oxide nanoparticles by using aqueous leaf extract of Mangifera indica to overcome the chemical synthesis. The reduction of precursors used for nanoparticles is activated by natural reducing agents present in plant extract which eliminates the neurotoxic reducing agents present in chemicals. The nanoparticles were assessed for their stability by varying parameters like pH, temperature, time and concentration. The highly stable nanoparticles were characterized using UV-visible spectroscopy, X-ray diffraction, Fourier transform infrared spectroscopy and field emission scanning electron microscopy with EDAX. Further the synthesized nanoparticles are investigated for photodegradation and antibacterial activity and found to be more effective.
