Effect of Synthesis Conditions on the Preparation of Ag/ZnTiO₃ via Sol-Gel Method and its Antibacterial Properties

Abstract:

Antibacterial materials based on nanotechnology have been attracted considerable attention by the scientific community. In this study, the sol-gel method was applied to prepare of antibacterial materials from tetra-n-butyl orthotitanate, zinc nitrate and ethylenediamine tetraacetic acid (EDTA) as a complexing agent. The effects of the synthesis conditions on the properties of the Ag/ZnTiO₃ samples such as the calcination temperature, the calcination time, pH value and ethylene glycol volume, were investigated. The obtained materials were characterized by powder X-ray diffraction (XRD) and their antibacterial activity against Staphylococcus aureus (S. Aureus) was evaluated. The results showed that the optimum conditions for Ag/ZnTiO₃ synthesis were: calcination temperature of 650°C, calcination time of 2 h, pH value of 4.5 and ethylene glycol volume of 4.5 mL.
