Abstract

紫外线催化 TiO2 消毒技术作为一种高效环保的高级氧化技术,通过紫外激发 TiO2 产生的活性氧(ROS)破 坏微生物结构,在饮用水净化、空气消毒及医疗器械灭菌等领域展现出巨大潜力。文中介绍了 TiO2 的制备方法、不 同晶型结构对催化性能的影响。针对材料实际应用受限于材料光吸收范围窄、光生载流子复合率高、催化剂回收困 难及复杂环境适应性差等问题,综述了不同提高 TiO2 光催化活性的改性方法。此外,还分析了影响消毒效果的关键 因素,探讨了该技术在不同领域的应用现状。尽管该技术已成功应用于水体病原体灭活、VOCs 降解及医疗环境净化, 但其规模化推广仍需开发全光谱响应材料、结合人工智能优化催化体系,并推动低成本绿色工艺。未来,通过多技 术集成与智能反应器创新,紫外线催化 TiO2 消毒技术有望在环境与公共卫生领域实现更高效、可持续的应用。
