BaTiO₃ powers with different morphologies, including nanoparticles, cubes, wires, and sheets were synthesized. The morphology and phase structure of as-synthesized samples were characterized by scanning electron microscopy (SEM), X ray diffraction (XRD), Fourier transform infrared spectra (FTIR), and UV visible(UV Vis) absorption spectra. The piezocatalytic activity of BaTiO₃ under different morphologies and catalytic conditions was compared, and the mechanism of differential piezocatalytic activity was explained based on finite element method simulation. The results show that the higher activity of BaTiO₃ nanosheets is due to the generated higher potential. The degradation of rhodamine B (RhB) dyes by BaTiO₃ nanosheets showed better catalytic activity when the solid content was 2 g·L^-1, the ultrasonic frequency was 40 kHz and the dye mass concentration was 5 mg·L^-1. Furthermore, the mechanism of piezocatalysis reveals that the hydroxyl radical (·OH) and superoxide radicals (·O₂^-) are the main reactive species in the degradation process by targeting the degradation of RhB.
