摘要：

The photocatalytic activity of ZnO and Sr2+ doped ZnO nanoparticles was evaluated by photocatalyic oxidation of methyl orange and methylene blue. The results show that the photocatalytic activity of Sr2+ doped ZnO was much higher than that of pure ZnO. The sample with mole ratio of Sr/Zn 1:2 show the maximum activity. The effect of heat treatment on photocatalytic activity of the samples was studied in the temperature range 400-800 degrees C and found that the sample calcined at 600 degrees C shows the maximum activity. The dependence of calcination time on the photo-catalytic activity was studied and observed that the best heat treatment time is 7 h.
