| Abstract: | Bismuth titanate powders are prepared by the citric--combustion method using bismuth nitrate and titanium butoxide as the starting precursors, and the effects of sintering temperature and the ratio of bismuth to titanium on their structure and photocatalytic activity were studied. The powders were characterized by X--ray diffractometry （XRD） and scanning electron microscopy （SEM）. The photoeatalyric property of the samples was probed by using the methyl blue as simulated contaminants. The results show that bismuth titanate powder prepared with the ratio of bismuth to titanium of 8 ： 1 at the sintering temperature of 873K has the best photocatalytic activity. |
