Effective photocatalytic antibacterial and degradation of Bi2MoO6/Bi4O5l2 driven by visible light

In this study, BMO/BOl composites are prepared using solvothermal and calcination methods, successfully establishing a stable heterojunction structure between the Bi 2 MoO 6 amd Bi 4 O 5 l 2 , the photocatalytic and adsorption properties of the material are also optimized. When degrading dyes and antibiotics, BMO/BOI-10% can remove 97% of RhB and approximately 80% of TCH within 10 min. When killing E. coli and S. aureus , it can still achieve 100% complete elimination of them within 10 min. We demonstrate the material's stability through cyclic testing under various conditions and identify its mechanism of action in polluted water treatment through free radical scavenging experiments, the results of safety tests also provide a basis for assessing the material's safety. we apply the material to treat polluted water in various environments. The results show that, compared to the control group, the material demonstrates highly significant effects in degrading organic pollutants and inhibiting bacterial transmission, fully validating its application potential and providing a reference for research in related fields. In the end of the study, the synergy between BMO/BOI-10% and other systems yields even more significant results, enabling the removal of 93% of RhB and 98% of S . aureus within 5 min using only 0.2 g/L of photocatalyst.
