Abstract:Piezoelectric catalysis refers to the process of using tiny mechanical energy to achieve catalysis. It can effectively use mechanical energy in the environment such as noise and vibration to degrade organic pollutants, decompose water to produce hydrogen and reduce carbon dioxide. This article mainly introduced the research progress of using piezoelectric catalytic effect to degrade organic pollutants. It summarized the principle of piezoelectric catalysis and the methods of catalytic system innovation, morphology control and heterojunction to improve catalytic efficiency. The most important thing was to describe the special structure of the piezoelectric-photocatalytic material system. Other application areas of piezoelectric catalysis were cited, and the research prospects were also prospected.
Key words: piezoelectric catalysis; degradation; organic dyes; synergistic catalysis; catalytic efficiency; catalytic mechanism; heterogeneous structure
