Comparative SEM Analysis Study of Titanium Dioxide (TiO2) Nanoparticles Synthesized by Sol-Gel Method

Abstract

This paper describes the comparative SEM Analyses study of various samples of nanoparticle Titanium Dioxide (TiO2) synthesized by the Sol-Gel method with different changes in the parameters. Titanium dioxide is not very reactive with chemicals and doesn't harm the environment, so it is widely used as a colour in industry. It comes in three forms: anatase, rutile, and Brookite. Scanning electron microscopy was used to examine the morphological changes of the produced TiO2 nanoparticles at various calcination temperatures as well as the precursor ratio. SEM analysis was carried out at 10 kV acceleration Voltage. According to the SEM results, the achievement of high temperatures, the alteration of the precursor ratio, and the presence of distinct contents of the two crystalline phases of titanium dioxide are the causes of the increase in particle size and the apparent aggregation of TiO2 nanoparticles. These results are in agreement with XRD results that showed the particles size of the anatase phase smaller than particles grown at the higher temperature.
