  • The rapid development of society has brought huge economic benefits, but also brought a series of ecological environment problems, such as water pollution, air pollution and pollutant discharge. Catalytic degradation is considered as an effective strategy to deal with various kinds of pollution. Compared with traditional photocatalysis, piezoelectric catalysis is a new catalytic method proposed in recent years. Through the piezoelectric catalytic convert mechanical energy into chemical energy is an effective means of solving the water pollution problem, large numbers of piezoelectric materials have been applied in the research of catalytic degradation of piezoelectric, including BaTiO3 nano powder as a kind of typical piezoelectric material, because of low cost, the advantages of strong piezoelectric activity, caused the wide attention of researchers. In this paper, the theory and origin of piezoelectric catalysis are summarized, some commonly used piezoelectric catalysis materials are listed and their applications are illustrated. Around BaTiO3, the basic structure, common preparation methods of nano-BaTiO3 powder, application in piezoelectric catalysis and some typical modification methods are introduced. Finally, the future development trend of BaTiO3-based nano-powders in piezoelectric catalysis field is prospected.
