“…It is worth noting that under the combined action of mechanical vibration and light irradiation, the recombination of elec-a trons and holes in piezoelectric materials with photocatalytic activity can be significantly inhibited by the built-in electric field, thus improving the photocatalytic activity. [21][22][23] Compared with the previous strategy, which can only provide limited functions, piezocatalysis does not need extra voltage and only uses low-frequency mechanical energy to generate piezoelectric potential. [24][25][26] Therefore, the synergistic coupling effect of piezo-photocatalysis came into being.…”

“…Based on variations in the production of active agents and reaction conditions, this can be categorized into electrocatalytic oxidation, ozone oxidation, photocatalytic oxidation, and Fenton/Fenton-like oxidation [47][48][49][50]. Among these, catalysis is recognized as a potent approach to water treatment, encompassing piezo-catalysis, photocatalysis, electrocatalysis, and bio-catalysis [51][52][53][54][55][56].…”

The efficient degradation of organic pollutants in diverse environmental matrices can be achieved through the synergistic application of piezo‐catalysis and photocatalysis. The focus of this study is on understanding the fundamental principles and mechanisms that govern the collaborative action of piezoelectric and photocatalytic materials. Piezoelectric nanomaterials, under mechanical stress, generate piezo‐potential, which, when coupled with photocatalysts, enhances the generation and separation of charge carriers. The resulting cascade of redox reactions promotes the degradation of a wide spectrum of organic pollutants. The comprehensive investigation involves a variety of experimental techniques, including advanced spectroscopy and microscopy, to elucidate the intricate interplay between mechanical and photoinduced processes. The influence of key parameters, such as material composition, morphology, and external stimuli on the catalytic performance, is systematically explored. This study contributes to the increasing knowledge of environmental remediation and lays the foundation for the development of advanced technologies using piezo and photocatalysis for sustainable pollutant removal.
