Study on the Thermal Treatment of Nano-Ag/TiO 2 Thin Film

Abstract

The photocatalytic degradation rates of methyl orange and antibacterial properties of nano-Ag/TiO 2 thin film on ceramics were investigated in this study. XRD was used to detect the structure of film to clarify the impacts on the rates and properties. The effect of film layers, heating temperature, heating time, and embedding of Ag + on the degradation rates and antibacterial properties were ascertained. The nano-Ag/TiO 2 film of 3 layers with AgNO 3 3% embedded and treated at 350°C for 2 h would exhibit good performance.
