摘要: This paper reports the preparation and characterization of titanium dioxide nanoparticles (TiO2-NPs) with pure anatase phases using polyol synthesis process. The state particle size are controlled by varying parameters such as precursor concentration, hydrolysis rate time. Nanoparticles were characterized X-ray diffractometry, TEM, FT-IR spectroscopy measure complex impedance spectroscopy. Their physicochemical properties investigated to optimize conditions. spectra exhibit broad peaks where TiO2 demonstrate very sharp peaks. structural XRD confirms that there is a formation TiO2-NPs at 550 °C crystalline in range 19–25 nm. crystallite core decreases concentration tetrachloride TiCl4 precursor. Electrical relaxation phenomenon material studied several temperatures.
