Abstract

Improved sol-gel method has been applied to prepare highly crystalline TiO2 colloidal nanoparticles with high photocatalytic reactivity. The precursor solution contained titanium (IV) isopropoxide (TTIP), 2-propanol. The sol was obtained through the hydrolysis of TTIP under the optimized conditions. FTIR, TEM and XRD were used to study the morphology, size, shape and crystallinity of prepared TiO2 sol. Experimental results have shown that the prepared sample has an anatase structure. It has a narrow size distribution between 2-5 nm which has been confirmed by X-ray diffraction pattern. To demonstrate the photocatalytic properties of TiO2 colloidal nanoparticles, the Methylene Blue (MB) photodecomposition test has been used. In this approach, the obtained photodecomposition reaction rate of Methylene blue under UV light is high and shows the prepared colloidal TiO2 sample has enough potential for photocatalytic applications. The photocatalytic property of the dried sol has been evaluated by inactivation test of Escherichia coli.
