摘要 以钛酸四丁酯和硝酸铋为原料,以氢氧化钠为矿化剂,采用水热法制备出了焦绿石相的钛酸铋(Bi2Ti2O7)复合材料压电催化剂;采用SEM和XRD表征了样品的形貌和晶相结构;以罗丹明B(Rh B)为目标降解物,研究了所制备样品的压电催化降解性能,并对其催化机理进行了探讨。结果表明,Bi2Ti2O7纳米材料机械振动对Rh B降解率达到87.8%;当掺杂纳米ZnO后,对Rh B的降解率达到96.9%,ZnO的掺杂有利于提高Bi2Ti2O7的活性。

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.
Key words:  Bi2Ti2O7    ZnO doping    piezoelectric catalytic performance    degradation rate
