Photodeposition of CoO_x nanoparticles on BiFeO₃ nanodisk for efficiently piezocatalytic degradation of rhodamine B by utilizing ultrasonic vibration energy.

ABSTRACT: Piezoelectric materials have received much attention due to their great potential in environmental remediation by utilizing vibrational energy. In this paper, a novel piezoelectric catalyst, CoO_x nanoparticles anchored BiFeO₃ nanodisk composite, was intentionally synthesized via a photodeposition method and applied in piezocatalytic degradation of rhodamine B (RhB) under ultrasonic vibration. The as-synthesized CoO_x/BiFeO₃ composite presents high piezocatalytic efficiency and stability. The RhB degradation rate is determined to be 1.29 h^-1, which is 2.38 folds higher than that of pure BiFeO₃. Via optimizing the reaction conditions, the piezocatalytic degradation rate of the CoO_x/BiFeO₃ can be further in
