Summary: In this study, we achieved remarkable piezo-photocatalytic activity over ultrathin Bi4O5I2 nanosheets and revealed the synergistic catalytic mechanism. We found that Bi4O5I2 has strong piezo-electricity through piezoelectric force microscopy (PFM) and COMSOL simulation analysis. The ultrathin nanosheets exhibited a piezo-photocatalytic efficiency for tetracycline hydrochloride (TH) degradation, which was 2.3-fold higher than the sum of single photocatalysis and piezocatalysis, and surpassed previously reported piezo-photocatalysts. Our in situ electrochemical and electron paramagnetic resonance (EPR) studies showed enhanced charge separation and transfer, as well as reactive species evolution (superoxide radicals and holes) in the piezo-photocatalytic reaction process, attributed to the piezoelectric field and band bending. This work highlights the impact of the piezoelectric field on enhancing photocatalytic performance and advancing our understanding of the synergistic piezo-photocatalytic mechanism.

Summary: In this study, twin-brush hierarchical structures of ZnO (TB-ZnO) were used for the first time as piezoelectric mesocrystals to activate peroxymonosulfate (PMS). Compared with common ZnO nanorods (NR-ZnO), TB-ZnO exhibited significantly enhanced performance for the degradation of ibuprofen (IBP) pollutants in the presence of PMS and ultrasonic vibration, and achieved a high PMS utilization efficiency surpassing existing catalysts. Experimental and theoretical results showed that the presence of oxygen vacancies and ordered mesoporous superstructures in TB-ZnO promoted electron transfer, lowered reaction barriers, and facilitated mass transfer, enabling more electrons to participate in PMS activation. These findings provide a new approach to improve the utilization efficiency of PMS in piezo-activation systems for environmental remediation.
