“…Second, certain dyes in the mix are synthetic and contain aromatic amines, which are known to be mutagenic and carcinogenic, posing additional environmental and health risks [18][19][20]. Metal complex dyes and certain catalysts, like antimony acetate, antimony trioxide, or glycol antimony, consist of heavy metals that have the propensity to dissolve in water, presenting a significant hazard due to their high toxicity [21][22][23]. That's why considering dyeing and printing wastewater is essential to prevent environmental damage and harm to organisms.…”

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.
