摘要：

In the present paper were established the optimum conditions for the synthesis of Ag-doped ZnO nanopowders. The 0.05% Ag-doped ZnO nanopowders were successfully synthesized by coprecipitation, followed by a washing-drying-calcination treatment. It was found that the optimum conditions for the preparation with high yield and high surface area were as follows: pH value 6.9-7.1, calcination temperature 400-500 degrees C and calcination time 2 h, respectively. The obtained nanopowders were investigated by X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR) and specific surface. The silver doping improves the antibacterial activity of ZnO nanopowders. Therefore the materials based on the obtained nanopowders represent an attractive opportunity for the construction industry.
