Biopreparation of titanium dioxide nanoparticles from Moringa oleifera Lam. Leaf extract and its applications
Keywords:
Titanium dioxide nanoparticles, Green synthesis, Moringa oleifera Lam, Photocatalytic activityAbstract
This research to study the preparation of titanium dioxide nanoparticles (TiO2 NPs) using leave extracts of Moringa oleifera Lam. The synthesized titanium dioxide nanoparticles were characterized by using X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), scanning electron microscopy (SEM), and Zeta particle size analysis. The formation of the synthesized TiO2 nanoparticles from the XRD spectra when compared with the confirmed standard spectra of titanium particles formed in the present experiments was in the form of nanocrystals, as evidenced by the peaks at 2theta of 24.9157◦ and 27.9629°. The FTIR spectrum of TiO2 nanoparticles displayed a prominent peak at 593 cm-1. SEM analysis of the synthesized TiO2 nanoparticles clearly showed that they were in clusters and irregular shape. The particle size analysis was found to be 238.9–381.5 nm. The degradation of methylene blue dye, titanium with nanoparticle size was tested. Can remove up to 97.4% of dye. This method represents a new alternative method for preparing environmentally friendly and low-cost nanoscale metals.
