【 摘 要 】

Ag/PbBiO2I nanocomposite was synthesized and firstly applied in piezocatalytic degradation of rhodamine B (RhB) under ultrasonic vibration. The two-dimensional structure endows PbBiO2I nanosheets piezoelectric property, so that it can drive the piezocatalytic reaction under ultrasonic vibration. The loading of Ag nanoparticles forms Schottky barriers between the Ag-PbBiO2I contact region, which improves the separation of charge carriers and subsequently increases the piezocatalytic efficiency. The RhB degradation rate of the optimal Ag/PbBiO2I sample is 0.0165 min−1, which reaches 6.8 times that of pure PbBiO2I. This work indicates that the PbBiO2I nanosheet shows promising potential in utilizing ultrasonic vibration energy.
