摘      要：It is a major constraint that complex synthesis methods limiting to the application of catalysts. Herein, a Ag particles in-situ deposited on the surface of BaTiO3 of Ag@BaTiO3 catalyst is synthesized via a facile method, which demonstrates outstanding catalytic properties. Investigations reveal that Ag deposit could increase carrier concentration, reduce the electronic impedance and enhance carrier’s separation efficiency under ultrasonic vibration, leading to superior piezocatalytic performance. Therefore, the typical pollutant Rhodamine B dye can effectively degraded by 95.4%, within 50 min of light and ultrasound. Moreover, the optimal amount of Ag loading could improve the cycling stability of the catalyst, which the degradation ratio remain at 81.9% after 5 even experience repeated high-frequency vibrations. This work provides a novel and easy implement strategy for designing high performance catalysts, and could be extended to other catalytic material. © 2023, The Authors. All rights reserved.
