Descripción
Sumario:Ag/PbBiO(2)I nanocomposite was synthesized and firstly applied in piezocatalytic degradation of rhodamine B (RhB) under ultrasonic vibration. The two-dimensional structure endows PbBiO(2)I 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-PbBiO(2)I contact region, which improves the separation of charge carriers and subsequently increases the piezocatalytic efficiency. The RhB degradation rate of the optimal Ag/PbBiO(2)I sample is 0.0165 min(−1), which reaches 6.8 times that of pure PbBiO(2)I. This work indicates that the PbBiO(2)I nanosheet shows promising potential in utilizing ultrasonic vibration energy.
