Piezoelectric photocatalysis can effectively suppress the recombination of electron holes during the course of photocatalysis, which has been widely applied in environmental and energy catalysis. Its advantage is that when the piezoelectric effect happens, a built-in electric field is formed inside the catalyst, which improves the separation efficiency of photogenerated charge carriers and obtains more excellent photocatalytic performance. The efficient conversion of mechanical energy to chemical energy can be realized through the synergistic effect of the piezoelectric effect, and photocatalysis is greatly significant in solving the energy crisis and providing environmental protection. Therefore, we organized a more complete review to better understand the mechanism and system of piezoelectric photocatalysis. We briefly introduce the principle of the piezoelectric effect, the existing types of piezoelectric photocatalysts, the practical application scenarios, and the future challenges and feasible methods to improve catalytic efficiency. The purpose of this review is to help us broaden the idea of designing piezoelectric photocatalysts, clarify the future research direction, and put it into more fields of environmental protection and energy reuse.
压电光催化能够在光催化过程中有效抑制电子空穴的复合，这已在环境和能源催化领域得到广泛应用。其优势在于，当发生压电效应时，催化剂内部会形成一个内建电场，这提高了光生电荷载流子的分离效率，并获得更优异的光催化性能。通过压电效应的协同作用，可以实现机械能向化学能的高效转化，压电光催化在解决能源危机和提供环境保护方面具有重大意义。因此，我们组织了一次更全面的综述，以更好地理解压电光催化的机理和体系。我们简要介绍了压电效应的原理、现有的压电光催化剂类型、实际应用场景以及未来的挑战和提高催化效率的可行方法。本综述的目的是帮助我们拓宽设计压电光催化剂的思路，明确未来的研究方向，并将其应用于更多的环境保护和能源再利用领域。
