Abstract
Metal oxide photocatalyst is one of the promising photocatalysts in the water remediation process. The present work is aimed at synthesizing the green production of TiO2 (G-TiO2) nanoparticles from mulberry plant extract. Plant phytochemicals serve a different role to produce the nanophase particles. The bioreductant is safer and noxious free compound for synthesizing the G-TiO2 nanoparticles. The synthesized G-TiO2 nanoparticles in anatase phase and their crystallite size of 24 nm were characterized from X-ray diffraction analysis. The Ti-O bonding and plant derivatives and their reduction were confined from FTIR analysis. The wide bandgap of G-TiO2 nanoparticles (3.16 eV) and their optical characterization were captured from UV-DRS analysis. The spherical surface morphology and their Ti and O elemental configurations were characterized from FESEM with EDX technique. The photocatalytic dye degradation was examined against methylene blue dye, and their pseudo-first-order kinetics were evaluated. The cyclic experiments declared their catalytic potential. The bacterial resistance of G-TiO2 nanoparticles was examined against gram-positive and gram-negative bacteria. Hence, the catalytic potential and bacterial stability of G-TiO2 nanoparticles are the powerful candidate for water remediation and biomedical applications.
