Abstract
The present invention discloses a preparation method of a silver-modified spiral Titanium Dioxide (TiO) nano-fiber photocatalyst, comprising the following steps: preparing a spiral TiOnano-fiber; preparing a nano-silver aqueous solution; and preparing a silver-modified spiral TiOnano-fiber photocatalyst. The photocatalyst is coupled with the spiral structure of the nano-fiber and nano-silver particles with a specific size, improving the photocatalytic activity of the photocatalyst. Moreover, the sterilizing and biological pollution resisting capacities of the photocatalyst are also improved through the modified nano-silver particles, and therefore, the photocatalyst can be widely applied to a deep sewage treatment system.
