Piezoelectric catalysis has been considered a promising technology in water pollution control. In this report, environmental-friendly (Bi1/2Na1/2)(1-x)BaxTiO3(BNBT-x) piezoelectric materials with the morphotropic phase boundary (MPB) were prepared by one-step solvothermal method. The piezocatalytic activities of the BNBT-x piezoelectric materials were examined by the degradation of RhB dye solution. The results demonstrate that the BNBT-6 catalyst with the MPB exhibit a higher piezocatalytic performance of up to 98.95% compared to pure BNT. In addition, the BNBT-6 catalyst exhibits good reusability, which is of great significance for practical applications. This work opens a route to design and develops high-performance piezocatalysts.
