The Photocatalytic Behavior of Bismuth Titanate Powders Prepared by the Citric-Combustion Method

Abstract:

Bismuth titanate powders have been prepared by the citric-combustion method using bismuth nitrate and tetrabutyl titanate as the starting materials, and the effect of sintering temperature and the ratio of bismuth to titanium on their structure and photocatalytic activity was studied. The powders were characterized by X-ray diffractometry (XRD) and scanning electron microscopy (SEM). The photocatalytic properties of the samples were probed by using the methyl blue as simulated contaminants. The results showed that bismuth titanate powder prepared at 873K has the best photocatalytic activity.
