Ultrasonic-Assisted Piezoelectricity by Barium Titanate Materials: Multi-Domain Application and Mechanism Exploration

Barium titanate-based materials serve as highly efficient catalysts in the realm of piezoelectric ceramics. With the aid of ultrasound, these piezoelectric ceramics have been widely used and exhibit remarkable potential in advancing wireless, precise control of therapeutic technologies, medical applications, and environmental pollutant control. There is a growing interest in leveraging these materials to develop innovative methods for degrading emerging contaminants, but limited articles have explored the feasibility of this application. As such, we review the progress of research in ultrasonic-assisted piezoelectric catalysis by barium titanate materials (BTO&US) and discuss the underlying catalytic mechanisms in various application scenarios. In addition, we outline its future research directions, focusing on crystal structure optimization, electronic density regulation, medium, and catalytic applications for the degradation of emerging contaminants. This review on BTO&US offers novel ideas and methodologies that contribute to the development and application of piezoelectric ceramics.
