Abstract:

With its advantages such as good stability, high efficiency and low cost, photocatalytic technology has been gradually applied in the field of water disinfection, where a series of reactive oxygen species generated by photocatalysts can effectively inactivate the pathogenic microorganisms in water. Because the structure and resistance of viruses are quite different from those of other microorganisms, this article only focuses on the research progress of photocatalytic materials for removing viruses in water. The oxidation and disinfection principles of photocatalytic technology are introduced, the advantages and disadvantages of traditional disinfection technology for viruses removal are discussed, and the applications of TiO₂-based photocatalysts and TiO₂-free photocatalytic materials are summarized. Finally, we conclude that the future photocatalytic materials should be developed in the directions of reducing preparation costs, improving photocatalytic efficiency, and enabling practical large-scale engineering applications.

摘要：

光催化技术凭借其稳定高效且成本低等优势，应用于水消毒领域的研究逐渐受到重视。光催化剂生成的一系列活性氧物种能有效灭活水中病原微生物。由于病毒与细菌等其他微生物结构、抗性等不同，因此本文着重综述了光催化材料应用于去除水中病毒的研究进展。介绍了光催化技术的氧化和消毒原理，评价了传统消毒工艺去除病毒的优缺点，总结了TiO₂基光催化剂和不含TiO₂的光催化材料的应用现状。最后展望未来光催化材料设计应以降低制备成本、提高光催化效率、能实际大规模工程化应用的方向发展。
