Abstract

<jats:title>Abstract</jats:title><jats:p>Green synthesis is an easy, safe, and environmentally beneficial nanoparticle creation method. It is a great challenge to simultaneously improve the capping and stabilizing agent carrier separation efficiency of photocatalysts. Herein, Zn-doped Titanium dioxide (TiO<jats:sub>2</jats:sub>) nanoparticles with high exposure of 360 nm using a UV/visible spectrophotometer were prepared via a one-step hydrothermal decomposition method. A detailed analysis reveals that the electronic structures were modulated by Zn doping; thus, the responsive wavelength was extended to 600 nm, which effectively improved the visible light absorption of TiO<jats:sub>2</jats:sub>. We have optimized the different parameters like concentration, time, and temperature. The peak for TiO<jats:sub>2</jats:sub> is located at 600 cm-<jats:sup>1</jats:sup> in FTIR. A scanning electron microscope revealed that TiO<jats:sub>2</jats:sub> has a definite shape and morphology. The synthesized Zn-doped TiO<jats:sub>2</jats:sub>NPs were applied against various pathogens to study their anti-bacterial potentials. The anti-bacterial activity of Zn-doped TiO<jats:sub>2</jats:sub> has shown robust against two gram-ve bacteria (<jats:italic>Salmonella</jats:italic> and <jats:italic>Escherichia coli</jats:italic>) and two gram + ve bacteria (<jats:italic>Staphylococcus epidermidis</jats:italic> and <jats:italic>Staphylococcus aureus</jats:italic>). Synthesized Zn-doped TiO<jats:sub>2</jats:sub> has demonstrated strong antifungal efficacy against a variety of fungi. Moreover, doping TiO<jats:sub>2</jats:sub> nanoparticles with metal oxide greatly improves their characteristics; as a result, doped metal oxide nanoparticles perform better than doped and un-doped metal oxide nanoparticles. Compared to pure TiO<jats:sub>2</jats:sub>, Zn-doped TiO<jats:sub>2</jats:sub> nanoparticles exhibit considerable applications including antimicrobial treatment and water purification.</jats:p>
