Abstract: A pyrochlore phase bismuth titanate composite piezoelectric catalyst is prepared by means of hydrothermal method using tetrabutyl titanate and bismuth nitrate as raw materials,sodium hydroxide as mineralizer.The morphology and crystal phase structure of the sample are characterized by SEM and XRD.Taking Rhodamine B as the target degradation product,the piezoelectric catalytic degradation performance of the prepared samples are evaluated,and the catalytic mechanism is discussed.The results show that the degradation rate of Rhodamine B by Bi2Ti2O7 nanomaterials mechanical vibration is 87.8%,and reaches 96.9% when nano-ZnO materials are doped in Bi2Ti2O7 nanomaterials,indicating that the doping of ZnO is beneficial to improve the activity of Bi2Ti2O7.
