Silica-based photocatalyst fiber having visible-light activity and process for the production thereof

   
   

A silica-based photocatalyst fiber having visible-light activity, which fiber comprises a composite oxide phase comprising an oxide phase (first phase) mainly made of a silica component and a titania phase (second phase), wherein the second phase contains a metal element other than titanium and the existent ratio of the second phase slopingly increases towards the surface of the fiber, and a process for the production thereof.

Una fibra silicona-basada del photocatalyst que tenía actividad de la visible-luz, que la fibra abarca una fase compuesta del óxido que abarca una fase del óxido (primera fase) hizo principalmente de un componente de la silicona y una fase del titania (segunda fase), en donde la segunda fase contiene un elemento del metal con excepción del titanio y el cociente existente de la segunda fase slopingly aumenta hacia la superficie de la fibra, y un proceso para la producción de eso.
