Water Purification in Dark Conditions Using Photocatalytic Light-leakage Type Plastic Optical Fiber
In this study, we fabricated a device that can be used for water purification in dark areas by combining a light-leakage type plastic optical fiber with a photocatalyst. The light-leakage type fiber was prepared by adding a scattering agent to the fiber core, and the titanium dioxide photocatalyst was composited by a two-layer coating method. Photocatalytic decomposition of methylene blue was performed by introducing light into the fiber without direct light irradiation.
