The field of photocatalysis has demonstrated numerous advantages in the domains of environmental protection, energy, and materials science. However, conventional modification methods fail to simultaneously enhance carrier separation efficiency, redox capacity, and visible light absorption solely through light activation due to the intrinsic band structure limitations of photocatalysts. In addition to modification methods, the introduction of an external field, such as a piezoelectric field, can effectively address deficiencies in each step of the photocatalytic process and enhance the overall performance. The assistance of a piezoelectric field overcomes the limitations inherent in traditional photocatalytic systems. Hence, this review provides a comprehensive overview of recent advancements in piezoelectric-assisted photocatalysis and thoroughly investigates the interaction between the alternating piezoelectric field and photocatalytic processes. Various ideas for synergistic enhancement of the piezoelectric and photocatalytic properties are also explored. This multifield catalytic system shows remarkable performance in stability, pollutant degradation, and energy conversion, distinguishing it from single catalytic systems. Finally, an in-depth analysis is conducted to address the challenges and prospects associated with piezoelectric photocatalysis technology.
光催化领域在环境保护、能源和材料科学等领域已展现出诸多优势。然而，由于光催化剂固有的能带结构限制，传统的改性方法无法仅通过光激发同时提高载流子分离效率、氧化还原能力和可见光吸收。除了改性方法外，引入外部场，如压电场，可有效解决光催化过程各步骤中的不足并提高整体性能。压电场的辅助克服了传统光催化系统固有的局限性。因此，本综述全面概述了压电辅助光催化的最新进展，并深入研究了交变压电场与光催化过程之间的相互作用。还探索了协同增强压电和光催化性能的各种思路。这种多场催化系统在稳定性、污染物降解和能量转换方面表现出卓越性能，使其有别于单一催化系统。最后，对压电光催化技术相关的挑战和前景进行了深入分析。
