Influence of Amount of Silver on the Structural and Optical Properties of TiO2 Powder Obtained by Sol–Gel Method


International Journal of Materials and Chemistry















In this paper five TiO2 powders prepared by sol–gel technique were analyzed being into consideration the modification of method of synthesis applied. As a precursors titanium (IV) buthoxide (TBOT) or titanium (IV) isopropoxide (TIPO) were used. The size of obtained pure TiO2 particles (called in paper TiO2–1 ÷ TiO2–5) was in the range 80–300 nm as it was confirmed by XRD, SEM and AFM techniques. Ag doped TiO2 (abbreviated herein as TiO2–2–Ag–y) was obtained using two methods of synthesis, where different amount of silver was added (1, 5 or 10% w/w). Additionally, the influence of method of the synthesis applied and amount of silver on the UV–vis properties of TiO2 was analyzed.
