Study on the Influence of Synthesis Temperature of Anatase TiO_2 Nanoparticles for Electrophoretic Deposition

摘要

The purpose of this research is to study the effect of synthesis temperature in order to produce anatase TiO_2 nanoparticles (NPs) without using strong acids. In this research TiO_2 nanoparticles was prepared by the hydrolysis and condensation of titanium (IV) isopropoxide in water at synthesis temperature of 0°C±0.1°C which produced anatase TiO_2 crystallite size of 4.66 nm. XRD (X-ray diffraction) was used to analyse the crystal structure of the TiO_2 and to calculate the crystallite size of the TiO_2 nanoparticles. Transmission electron microscope (TEM) was also used to characterise the morphology of the TiO_2 nanoparticles.
