In this paper, the antibacterial properties of TiO2 photocatalysts modified by 3-aminopropyltriethoxysilane (APTES) are presented. It has been observed that the APTES modification enhancement of antibacterial efficiency (against Escherichia coli ATCC 29425) under artificial solar light (ASL). The results showed that all modified titania had higher disinfection efficiencies than starting TiO2. For TiO2-4h-120 °C-300 a total sample elimination of the E. coli was achieved after 180 min of ASL irradiation. Improvement of antibacterial properties was attributed to the changes in the surface properties, i.e. zeta potential.

APTES修饰的TiO 2纳米颗粒的抗菌作用

本文介绍了3-氨基丙基三乙氧基硅烷(APTES)改性的TiO 2光催化剂的抗菌性能。已经观察到在人工太阳光(ASL)下,APTES修饰增强了抗菌效率(相对于大肠杆菌ATCC 29425)。结果表明,所有改性二氧化钛均比起始TiO 2具有更高的消毒效率。对于TiO 2 -4h-120°C-300,在ASL照射180分钟后,可以完全消除大肠杆菌的样品。抗菌性能的提高归因于表面性能(即ζ电势)的变化。
