Influence of Surfactants on TiO2 Nanoparticles Grown by Sol-Gel Technique

Davoud Dastan and N. B. Chaure
Abstract—TiO2 nanoparticles were prepared at room temperature by sol-gel method. In the current work, different surfactants such as Acetic Acid (AA), Oleic Acid (OA), and Oley amine (OM) were used for the preparation of TiO2 nanoparticles. TiO2 powder was collected by centrifuging precipitation obtained during gel formation. The powder was thoroughly cleaned few times in ethanol and annealed at 550o C and 950o C at specific time. I-V measurement is used to investigate the electrical properties of TiO2 pallets. In order to elucidate the influence of using these surfactants, the structural and optical properties of powder were investigated by means of X-ray diffraction (XRD), U-v visible, and Photoluminescence (PL). It was found that annealing could improve the crystallization of TiO2 powders and accelerated the phase transformation from anatase to rutile phase but surfactants do not change the particle size and energy band gap of titania.

Index Terms—TiO2 Powder, sol-gel, surfactants, annealing, electrical, optical, and structural properties.
