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.

The present research work reports the facile and green synthesis of TiO2 nanoparticles from Phyllanthus niruri leaf extract using the coprecipitation method. The plant biomolecules were responsible for the nanoproduction and exhibited reduction and stabilization activity. The green synthesized TiO2 nanoparticles were analyzed in various characterization methods. The crystalline size (23 nm) and anatase phase of TiO2 nanoparticles were analyzed from X-ray diffraction study. The reduction and stabilization response functional group of TiO2 nanoparticles was studied from FTIR analysis. The optical properties of TiO2 nanoparticles were constructed from the UV-DRS technique, and their calculated bandgap is 3.16 eV. The spherical morphology and their existing materials were identified using FESEM with EDX. The catalytic activity of TiO2 nanoparticles was examined against methylene blue dye under ultraviolet and visible light irradiation. It was detected that ultraviolet irradiation showed higher photocatalytic activity than visible light irradiation. In addition, visible light irradiation provides the above 90 percentage degradation of methylene blue dye. Hence, TiO2 nanoparticles were proposed as a potential catalyst of photocatalytic dye degradation application and water remediation activities.
