Research progress of piezocatalysis in energy and environment fields

Because it can simulate vibration in natural conditions, piezocatalysis has been a research hotspot in solving environmental and energy issues in recent years. Significant progress has been made, which needs to be re-summarized and reorganized to present a concise and logical work to readers. Therefore, in this review, recent progress of reported piezocatalysts (such as oxide, perovskite, sulfide, PVDF, MOFs and COFs), the way to enhance the performance of piezocatalysis (such as defects, heterojunctions, and piezo-coupled photocatalysis), and the application of piezocatalysis in environmental and energy fields (such as dyes, pesticides and antibiotics, heavy metal, piezocatalytic hydrogen production, and piezocatalytic CO₂ reduction), have been summarized. Finally, the future development trends of piezocatalysis are prospected and discussed.
