The main purpose of study was to provide a common synergy using Ag+-doped calcium phosphate powder and high-temperature-stable TiO2 for antibacterial and photocatalytic tile applications. Thermally stable SiO2-modified TiO2 active layer was deposited on Ag+-activated ceramic tiles by spray coating. The results showed that a nearly 100% cleanability degree was detected for SiO2-modified TiO2 (TS)-coated antibacterial tiles when compared uncoated and unmodified TiO2-coated tiles. Antibacterial tests and colorimetric analyses indicated that ceramic tiles provide both antibacterial and photocatalytic properties simultaneously.
