Enhancing Photocatalytic Activity and Biological Applications of TiO2 Nanoparticles Using Moringa Oleifera Leaf Extract

The biosynthesis of nanoparticles is an important research area focused on developing innovative, cost-effective, efficient, and environmentally friendly synthesis techniques with a wide range of applications. This study employs a straightforward and practical method to produce TiO 2 nanoparticles (NPs) for use in photocatalysis, antibacterial, antifungal, and antidiabetic applications. It utilizes extract-assisted biosynthesis with Moringa oleifera . To enhance the material and evaluate the impact of bioinspiration on various parameters, the resulting TiO 2 NPs undergo calcination at 500 °C. Structural confirmation, bandgap analysis, and functional group studies of MO/TiO 2 ( Moringa oleifera /TiO 2 ) nanoparticles are conducted using XRD, UV-DRS, FT-IR, and PL analysis. To examine the surface morphological characteristics of the anatase TiO 2 nanoparticles, SEM and TEM-EDS electron microscopy analyses were accomplished. The produced TiO 2 nanoparticles are also assessed for their photocatalytic and antidiabetic properties. Photocatalytic activity is determined by decolorizing methylene blue dye in the presence of sunlight, revealing that optimal conditions for complete color removal involve using 0.3 g of TiO 2 and a concentration of 4 × 10 − 5 M at pH 7. A total decolorization efficiency is achieved after 180 min in the presence of MO/TiO 2 . The biosynthesized Moringa oleifera leaf extracted TiO 2 (MO/TiO 2 ) was used for photocatalytic and biomedical applications. MO/TiO 2 exhibited the best photocatalytic activity and showed maximum inhibitoin in invitro antidiabetic activity. Invivo antidiabetic activity showed the Moringa oleifera leaf-extracted TiO 2 catalyst significantly reduced blood glucose levels.
