Abstract
The present invention discloses a novel photocatalytic optical fiber and a novel method for activating the photocatalytic optical fiber. The photocatalytic optical fiber comprises at least an optical fiber having a core and a light input end, a photocatalytic layer including photocatalyst disposed partially or entirely on the core, wherein light is introduced from the light input end into the core and the light reflects repeatedly inside of the core, wherein said light leaks gradually from the core to the photocatalytic layer, and wherein the photocatalytic layer is activated by irradiation of the light.
