Preparation of Ag/Zn 2 TiO 4 and its antibacterial activity on enamel tile

In this study, Ag/Zn 2 TiO 4 powder with uniform size (< 50 nm) and a specific surface area of 16.16 m 2 g −1 was synthesized by sol–gel method and coated on enamel tiles to investigate its antibacterial activity against Escherichia coli and Staphylococcus aureus. Results obtained from XRD patterns and the curve fitting of XPS spectra revealed that silver metal and its oxides are presented in the synthesized powder. The enamel tiles coated by Ag/Zn 2 TiO 4 exhibited good antibacterial activity against both bacteria. Besides, the Ag/Zn 2 TiO 4 coating improved the surface mechanical properties of the enamel tiles.
