摘    要:压电催化是指利用微小机械能实现催化的过程,它能够有效利用环境中的机械能如噪声、震动等降解有机污染物、分解水制氢和还原二氧化碳。本文主要概述了压电催化的原理,介绍了利用压电催化效应降解有机污染物的研究进展,总结了催化体系创新、形貌调控和异质结构等提高催化效率的方法,特别对压电-光协同催化材料体系的特殊结构进行了描述,并拓展介绍压电催化的其他应用领域,对研究前景进行了展望。

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.
