SnO2-doped TiO2 nanostructured thin films with antibacterial properties

TiO2-based nanostructure SnO2-doped coating have been prepaed by sol-gel method. The thin films were deposited on glass substrates by dip-coating process at room temperature with the drawing speed of about 1.25 mm/s. The coated samples were dried at room temperature for 24 h and calcined at the temp...

Description
Summary:TiO2-based nanostructure SnO2-doped coating have been prepaed by sol-gel method. The thin films were deposited on glass substrates by dip-coating process at room temperature with the drawing speed of about 1.25 mm/s. The coated samples were dried at room temperature for 24 h and calcined at the temperature of 600 °C for 2 h with a heating rate of 10 °C/min. All the synthesized thin films were thoroughly characterized by XRD, EDX and SEM analysis. The efficiency of antibacterial activity was evaluated by the inactivation of E.coli. The bacterial removal efficiency reached 60% at the optimum concentration of SnO2 (about 1 mol%) after 3 h UV irradiation. The antibacterial behavior of the doped TiO2 thin films was explicitly observed using SEM and cell wall damage was found.
