Research on the Sol-Gel Method of Preparing Ternary Nano SiO₂-Al₂O₃-TiO₂ Materials

Abstract:

Tetraethyl orthosilicate (TEOS), butyl titanate [Ti (OBu)₄] and aluminium isopropoxide were used as molecular precursor of ternary nanoSiO₂-Al₂O₃-TiO₂ materials. The influences of temperature and the dosage of compounds on the characteristic of ternary nanomaterials were investigated. Transmission electron microscopy (TEM), x-ray diffraction (XRD) and Fourier transform infrared spectroscopy (FTIR) were employed to investigate the characteristics of the nanomaterials synthesized by the sol-gel method. In addition, the adsorption of nanomaterials for different kinds of surfactants was also studied. Results revealed that the influences of temperature, compounds dosages and water on the size of ternary nanomaterials had a significant impact. With the increase of ammonia dosage, the concentration of the OH^- ion became higer, and system showed a faster reaction rate. The higer temperature of the system was, the larger size of the ternary nanomaterials was. Moreover, the higer tempreature woule also lead to divide into layer and precipitate. Optimal parameters can be chosen to prepare monodispersed ternary nanoSiO₂-Al₂O₃-TiO₂ materials. Results also showed that the surface characteristic of ternary nanoSiO₂-Al₂O₃-TiO₂ particles differed from nanosilica, which manifested in forms of the adsorption dosage of surfactants.
