Abstract Piezocatalysis, governed by piezo‐potential within piezoelectrics, has gained prominence for reactive oxygen species (ROS) generation, which is significant to environmental and biological applications. However, designing piezocatalysts with excellent piezocatalytic performance in a wide temperature efficient charge carrier separation ability still challenging. Herein, eco‐friendly BaTiO 3 (BT)‐based perovskite ferroelectrics tailored multiphase coexistence range are constructed boost higher piezoelectricity large piezo‐potential, attributed decreased polarization anisotropy flat Gibbs energy profile. Elevated designed BT‐based piezocatalyst guarantees high‐efficient generation rate of •OH (200 µmol g −1 h ) •O 2 − (40 ultrasound stimulation, 3.5 times more than that pure BT.

Recently, piezoelectric-based catalysis has been demonstrated to be an efficient means and promising alternative sunlight-driven photocatalysis, where mechanical vibrations trigger redox reactions. Here, 60 nm-size BiFeO3 nanoparticles are shown very effective for piezo-degrading Rhodamine B (RhB) model dye with record degradation rate reaching 13 810 L mol-1 min-1 , even 41 750 (i.e., 100% RhB within 5 min) when piezocatalysis is synergistically combined sunlight photocatalysis. These piezocatalytic also versatile toward several dyes pharmaceutical pollutants, over 80% piezo-decomposition 120 min. The maintained high piezoelectric coefficient low dielectric constant, high-elastic modulus, the nanosized shape make these extremely piezocatalysts. To avoid subsequent secondary pollution enable their reusability, further embedded in a polymer P(VDF-TrFE) matrix. as-designed flexible, chemically stable, recyclable nanocomposites still keep remarkable piezo-photocatalytic performances 92% degradation, respectively, 20 min).
