It is a major constraint that complex synthesis methods limit the application of catalysts. Herein, Ag/BaTiO catalyst is synthesized via a facile method, which demonstrates the outstanding catalytic properties. Investigations reveal that Ag-loading BaTiO could increase carrier concentration, reduce the electronic impedance and enhance carrier’s separation efficiency under ultrasonic vibration, leading to superior piezocatalytic performance. Therefore, Ag/BaTiO catalyst presents the high degradation efficiency of 95.4 % in 50 min for RhB dye solution at light illumination and ultrasonic vibration. Moreover, when Ag content is 0.33 %, the degradation ratio of the sample still remains 81.9 % after 5th cycles, which indicates Ag/BaTiO catalyst has good stability. This work provides a novel and easy implement strategy for designing high performance catalysts, and could be extended to other catalytic material.

BaTiO3 上低温一步合成银纳米颗粒以实现协同压电光催化性能

复杂的合成方法是限制催化剂应用的一大制约因素。在此，Ag/BaTiO催化剂通过简单的方法合成，表现出优异的催化性能。研究表明，负载Ag的BaTiO在超声振动下可以增加载流子浓度，降低电子阻抗，提高载流子分离效率，从而具有优异的压电催化性能。因此，Ag/BaTiO催化剂在光照和超声波振动下对RhB染料溶液在50分钟内呈现出95.4%的高降解效率。此外，当Ag含量为0.33%时，第5次循环后样品的降解率仍保持在81.9%，这表明Ag/BaTiO催化剂具有良好的稳定性。这项工作为设计高性能催化剂提供了一种新颖且易于实施的策略，并且可以扩展到其他催化材料。
