摘要
The dispersed, uniform and well stable AgBr nanoclusters were successfully prepared by ester-terminated PAMAM dendrimers as template. The results of TEM images and Brus' equation show that the size and morphology of AgBr nanoclusters could be effectively controlled by the molar ratios of Ag+:PAMAM dendrimers to meet the demands in different applications. The degradation of methyl oranges was also studied using AgBr nanoclusters with different sizes as the photocatalyst. The AgBr nanoclusters thus prepared showed much better catalytic activity and the catalytic activity increased with the decrease in the AgBr nanocluster size.
