| Abstract Scope |
Ag-doped MgO/TiO2 nanoparticles were successfully prepared via hydrothermal precipitation using titanium sulfate, magnesium chloride and silver nitrate as raw materials. The effects of various conditions on the preparation process of the Ag-doped MgO/TiO2 nanoparticles are investigated. The results showed that the optimal conditions were as follows: pH 9.0, mass ratio of titanium to silver 0.02, mass ratio of titanium to magnesium 2:1, reaction temperature 80℃, mass ratio of surfactant to titanium and magnesium 3%, calcination temperature 500℃.The as-obtained Ag-doped MgO/TiO2 nanocomposites were well characterized by X-ray diffraction, scanning electron microscopy and energy dispersive X-ray. The antibacterial experiments exhibit that the composite has a higher antibacterial activity than that of both the Ag-doped TiO2 nanoparticles and the mechanical mixture of Ag-doped TiO2 and MgO. |
