An emerging, environmentally friendly and sustainable method of decomposition wastewater urgently needs to be proposed due to the environmental crisis and the limitations of traditional treatment technologies. The piezocatalysis which convents vibration energy into electrical energy in dealing with dye wastewater is considered as a promising technology for environmental wastewater treatment owing to its environmental friendliness and sustainability. Piezocatalytic BaTiO₃ catalyst, with the advantages of high stability, environment friendly and easy to adjust morphology, is an ideal candidate for the effective decomposition of harmful organic wastewater. Meanwhile, there are many strategies to enhance the piezocatalytic performance of BaTiO₃ catalysts, including controlling morphology, doping element, electrically-poling, building heterostructure, coating noble metal, mixing carbon, composing polymer scaffold and increasing active sites. In this review, the synthesis of piezoelectric BaTiO₃ catalysts, the mechanism of BaTiO₃ piezocatalysis for wastewater treatment, the piezocatalytic energy sources of the BaTiO₃-based materials and the strategies of enhanced BaTiO₃-based piezocatalysis performance are introduced. Finally, the conclusions and perspectives of the BaTiO₃-based piezocatalysis are put forward to providing a direction for the future work.
