Production and characterization of titanium oxide nanoparticle using extract of macrophytic alga

Abstract

This study described a “green chemistry” synthesis of titanium oxide nanoparticle (TiO2-NP) using environment-friendly reducing agents that were from Elodea canadensis. The obtained TiO2-NP has an intense surface plasmon reverberation band at ~ 250 nm with UV–visible spectroscopic investigation which showed the intactness of TiO2-NPs. The morphological behaviour of TiO2-NPs was watched beneath field-emission scanning electron microscopy and transmission electron microscopy, shown that TiO2-NPs have a spherical pattern with a normal estimate of ~ 25 nm in breadth. The occurrence of the critical elements was pinpointed by energy-dispersive X-ray spectroscopy study, which displays the predominant titanium and oxide elements. Further support with a defined morphology and size distribution was rendered by atomic force microscopy and 3D high-power microscopy analyses. X-ray powder diffraction and chosen area electron diffraction examinations affirmed that TiO2-NPs are crystal clear in macrocosm. X-ray photoelectron spectroscopy study was uncovered natural composition of the TiO2-NPs, displaying Ti 2p crested at 458.48 eV with C1s crest for the catalyst that was shaped into a C–H constitute at 284.88 eV. The O 1s spectra moreover were displayed with authoritative vitality at 532.28 eV. XRD analysis gave proportion phase as 75%:25% for anatase and rutile. DLS showed polydispersity index esteem of − 1.23, and zeta potential for green synthesized Ti2O-NPs was − 3.87 mV. A broad hydroxyl peak was identified, and prominent peaks were notified at 1631.78 cm−1 and 3454.51 cm−1 by Fourier-transform infrared spectroscopy analysis.
