AI Article Synopsis
- The research focused on creating S-scheme heterojunctions, specifically BiSnO/β-BiO photocatalysts, to improve environmental cleanup, particularly in degrading tetracycline hydrochloride.
- The optimized photocatalysts showed a degradation efficiency of 95.5%, significantly outperforming β-BiO alone by 2.68 times due to better separation of photoelectron-hole pairs and enhanced reactive site exposure.
- Additionally, the BiSnO/β-BiO heterojunction demonstrated impressive stability, maintaining over 89.7% efficiency after five cycles of degradation processes.
Article Abstract
Fabrication of S-scheme heterojunctions with enhanced redox capability offers an effective approach to address environmental remediation. In this study, high-performance BiSnO/β-BiO S-scheme heterojunction photocatalysts were fabricated via the in situ growth of BiSnO on β-BiO microspheres. The optimized BiSnO/β-BiO (BSO/BO-0.4) degradation efficiency for tetracycline hydrochloride was 95.5%, which was 2.68-fold higher than that of β-BiO. This improvement originated from higher photoelectron-hole pair separation efficiency, more exposed active sites, excellent redox capacity, and efficient generation of O and OH. Additionally, BiSnO/β-BiO exhibited good stability against photocatalytic degradation, and the degradation efficiency remained >89.7% after five cycles. The photocatalytic mechanism of BiSnO/β-BiO S-scheme heterojunctions was elucidated. In this study, we design and fabricate high-performance heterojunction photocatalysts for environmental remediation using S-scheme photocatalysts.
