摘要:

光催化纳米TiO2以其出色的光催化、化学稳定性以及广谱抗菌性受到科研人员的青睐。然而,其存在的一些问题,如宽带隙、高过电位和光生载流子快速复合等限制了其光催化性能。本文综述了近年来TiO2光催化在抗菌方面的研究进展。对纳米TiO2光催化抗菌作用机理进行了探讨,并讨论了提高TiO2光催化抗菌活性的几种策略,包括进行纳米TiO2结构设计、光的调控、掺杂金属离子、掺杂非金属离子、贵金属修饰和偶联其他材料。 改性TiO2光催化剂显著抑制了细菌细胞的生长,在生物医学工程领域具有独特的应用前景。

Abstract:

Photocatalytic nano-TiO2 is favored for its excellent photocatalysis, chemical stability and broad-spectrum antibacterial properties. However, some problems, such as wide gap, high overpotential and fast recombination of photocarriers, limit its photocatalytic performance. This paper reviews the recent progress of TiO2 photocatalysis in antibacterial research. The mechanism of photocatalytic antibacterial activity of nano-TiO2 is discussed, and several strategies to improve the photocatalytic antibacterial activity of nano-TiO2 are discussed, including the structural design of nano-TiO2, the regulation of light, the doping of metal ions, the doping of non-metal ions, the modification of precious metals and the coupling of other materials. The modified TiO2 photocatalyst inhibits the growth of bacterial cells significantly, which has a unique application prospect in biomedical engineering.
