Green Synthesis of TiO2 Nanoparticles using Averrhoa Bilimbi Fruit Extract and their Applications in Photocatalytic Dye Degradation and Anti-bacterial Activities

Abstract

Due to their numerous distinctive characteristics, nanostructured materials are currently a crucial topic of research. One of the most promising materials today are TiO2 nanostructures, which are one among the transition metal oxides. Due to the absence of any potentially dangerous ingredients and commercially viable procedure, green approaches of nanoparticle synthesis have significant benefit over traditional approaches. The present work reported, the photocatalytic as well as anti-bacterial activity of green synthesized titanium dioxide (TiO2-NPs). An aqueous fruit extract of Averrhoa bilimbi as a capping as well as reducing agent, is utilized for the synthesis of TiO2-NPs. The prepared TiO2-NPs have been characterized by spectral methods using powder XRD (X-ray diffraction) and FTIR (Fourier transforms infrared spectroscopy). Morphological characterization by SEM analysis showed that the synthesized was spherical structure with an average particle size of 60 nm. The photocatalytic dye degradation and anti-bacterial activity have been performed and the result revealed the impressive capability of TiO2-NPs. Hence, the current research work offers a futuristic outlook on a green photocatalysts for profound applications.
