摘要：

利用滴度测定和透射电镜观察研究了365 nm的紫外光照射下TiO2对流感病毒(H1N1)的灭活性能, 并结合催化剂样品的XRD分析、 N2气吸附性能测定及其在实验条件下的表面Zeta电势的测量结果, 探讨了催化剂用量、 焙烧温度、 比表面积以及表面电性与灭活性能的关系. 研究结果表明, 400 ℃时焙烧的TiO2对H1N1的灭活性最好; TiO2的表面电性对灭活性有显著影响; TiO2对H1N1的光催化灭活作用首先发生在H1N1的纤突部分, 纤突部分的破坏导致H1N1的失活, 分解直至矿化.

Abstract:

In this paper the inactivation efficiency of TiO2 on H1N1 influenza virus under 365 nm UV illuminations was reported. Hemagglutination tests were used to determine the change of the titer of H1N1 and TEM were used to observe the deformation of H1N1 during photocatalysis. TiO2 photocatalysts were prepared by a modified sol-gel method and characterized by XRD, BET and Zeta potential measurements. The dependence of inactivation efficiency on dosage, calcinations temperature and surface charge state of the photocatalysts was investigated. The results show that TiO2 calcinated at 400 ℃ had the best performance and the surface charge state of the photocatalysts could influence the inactivation efficiency significantly. TEM micrographs reveal that H1N1 was attacked at its surface projections and it could be decomposed and mineralized for a longer photocatalytic treatment.
