Characterization of Titanium Dioxide Nanoparticles Synthesized By Microwave Method

Abstract

In this study, titanium dioxide (TiO₂) nanoparticles were fast and cheaply synthesized using microwave methods. Titanium isopropoxide (Ti[OCH(CH₃)₂]₄) was used as a precursor and deionized water (DW) was used as the solvent and reduction agent for sub-micrometer particle production after 5 minutes annealing at 400 °C for 1 hour using a 1200W commercial microwave instrument. The structural characterization tests showed that the anatase phase is the dominant in the prepared TiO₂ nanoparticles. Large TiO₂ surface area of 72.727 to 108.28 m²/g was confirmed. Spherical and irregular particles with uniform distribution and average diameters of 52.707, 65.602, and 82.095 nm were shown. Highly-pure TiO₂ nanoparticles with strong Ti and O peaks were produced.
