摘要： Superbacteria, which pose a severe threat to human health, necessitates the development of efficient antimicrobial materials. Bismuth oxyhalide (BiOX, X = Cl, Br, I) composite nanomaterials have emerged as promising photocatalytic antibacterial agents due to their unique layered structure, visible-light responsiveness, and tunable electronic properties. We systematically explores the structure-property relationships of BiOX, emphasizing the role of morphology, crystal facets, and electronic structures in enhancing antibacterial performance. We comprehensively analyze the underlying antibacterial mechanisms, including ROS generation, direct redox interactions, photothermal effects, and metal ion release. Additionally, we critically assess recent modification strategies, such as metal doping, heterojunction construction (Type II, Z-scheme, S-scheme), and defect engineering. These strategies significantly improve light absorption, charge separation efficiency, and ROS generation, thereby enhancing antibacterial efficacy. Furthermore, we highlight the emerging biomedical applications of BiOX-based materials, including tumor cell killing and wound healing, by leveraging both photocatalytic and photothermal effects. Finally, we outline the current challenges and future research directions for real-world applications. This review aims to provide a comprehensive understanding of BiOX-based photocatalysts, offering valuable insights for the development of efficient, durable, and sustainable antibacterial nanomaterials for biomedical applications.
