Traditional antimicrobial methods, such as antibiotics and disinfectants, may cause adverse effects, such as bacterial resistance and allergic reactions. Photocatalysts based on titanium dioxide (TiO) have shown great potential in the field of antimicrobials because of their high efficiency, lack of pollution, and lack of side effects. This paper focuses on the antimicrobial activity of TiO under different light sources. To improve the photocatalytic efficiency of TiO, we can reduce electron-hole recombination and extend the photocatalytic activity to the visible light region by doping with different ions or compounds and compounding with polymers. We can also improve the surface properties of materials, increase the contact area with microorganisms, and further enhance the resistance to microorganisms. In addition, we also reviewed their main synthesis methods, related mechanisms, and main application fields to provide new ideas for the enhancement of photocatalytic microorganism performance and application popularization in the future.
传统的抗菌方法，如抗生素和消毒剂，可能会产生不良反应，如细菌耐药性和过敏反应。基于二氧化钛（TiO₂）的光催化剂因其高效、无污染和无副作用，在抗菌领域显示出巨大潜力。本文重点研究了TiO₂在不同光源下的抗菌活性。为提高TiO₂的光催化效率，我们可以通过掺杂不同离子或化合物以及与聚合物复合来减少电子-空穴复合，并将光催化活性扩展到可见光区域。我们还可以改善材料的表面性质，增加与微生物的接触面积，并进一步增强对微生物的抗性。此外，我们还综述了它们的主要合成方法、相关机理和主要应用领域，为未来提高光催化微生物性能及应用推广提供新思路。
