Synthesis and Characterization of Controlled Size TiO2 Nanoparticles via Green Route using Aloe vera Extract

Titanium dioxide is an important semiconductor material for wide range of solar energy conversion applications. However, it is limited due to its high bandgap as well as high charge carrier recombination rate under illumination. This can be overcome partly by controlling the size of the particle via green synthesis route using Aloe vera gel extraction, wherein the kinetics and thermodynamics are equally modulated. The synthesized particles were characterized using different characterization techniques such as SEM, TEM, XRD, UV-Vis, and FTIR. The outcomes of present work will help to design more pronounced synthesis protocols for production of highly mono dispersed TiO2 nanoparticles for various electro/photoelectrochemical applications.
