| description | The present study provides an environmentally benevolent synthesis of titanium dioxide nanoparticles (TiO2 NPs). Morphological characteristics of the fabricated nanoparticles were assessed by using X-ray diffraction (XRD), Fourier-transform infrared spectroscopy (FTIR), scanning electron microscopy (SEM), and UV-Spectroscopy. The XRD pattern of the synthesized nanoparticles showed that the nanoparticles had a tetragonal crystalline structure with a particle size of 20–40 nm. The photocatalytic efficacy of the developed nanomaterials was investigated in relation to indigo carmine, bromothymol blue, and rhodamine b dye. The presence of a photocatalyst leads to an improved performance, causing a decline in dye concentration with increasing irradiation time. The highest dye degradation of about 95 % was observed against indigo carmine dye. The green synthesized TiO2 NPs exhibited a significant zone of inhibition (23 mm) in antibacterial activity against Bacillus at the concentration of 70 mg/mL. The developed nanoparticles demonstrate 81.29 % DPPH radical scavenging activity at the concentration of 60 μg/mL. |
