Abstract Piezoelectric materials offer great promise due to their ability generate electric fields under mechanical stress, producing surface charges that drive otherwise kinetically sluggish redox reactions. The strained surfaces of these provide a unique advantage in controlling product selectivity and enabling reaction pathways are unattainable with conventional methods. This perspective highlights advancements, challenges, the future potential piezoelectric synthetic organic chemistry, focus on designing optimized for piezocatalyzed synthesis. Piezocatalysis is industrially relevant because its operational simplicity, mild, gram scale synthesis reusable catalysts, minimal solvent use, air tolerant conditions. It involves cycles facilitate one electron events without requiring light exposure or electrical bias. Despite significant progress, many fundamental aspects yet be fully understood. One example correlation between piezoelectricity catalytic activity, which not always linear, as demonstrated by comparison tetragonal cubic BaTiO₃. While BaTiO₃ piezoelectric, it shows excellent activity certain reactions such arylation, dicarbonylation, cyclization mechanochemical conditions comparable Considering all aspects, this aims stimulate discussion advance promising field right direction.

Piezocatalysis is a promising technology for converting mechanical energy to chemical energy. Two-dimensional (2D) piezoelectric materials, with their large surface area, high charge mobility, and good flexibility, are among the most candidates in piezocatalysis. In this work, first time, we report Bi2O2Se nanosheets (NSs) an average thickness of ~8 nm lateral size ~160 efficient piezocatalytic H2O2 production from water oxygen under force induced by ultrasonication. The NSs achieved rate 1033.8 μmol/g/h using ethanol as sacrificial agent, significantly surpassing that its bulk-sheet counterpart. Our results provide novel potential 2D material offer valuable guidance design development high-efficiency driven water.
