摘要： A method for preparing optical fibers formed with high-particle-coated porous polymeric outer coating layer is provided. The method includes preparing a coating suspension solution by dispersing a plurality of particles into an organic solvent system, immersing one or more optical fibers into the coating suspension solution, removing the one or more optical fibers from the coating suspension solution to form high-particle-coated porous polymeric outer coating layer after drying. Concentrations and compositions of the particles in the coating suspension solution, concentrations and compositions of the organic solvent system, the period of time of immersing, or the external environment are adjusted such that the optical fibers is formed with high-particle-coated polymeric outer coating layers having desirable coating masses, coating thicknesses, or coating morphologies.

摘要： A system to produce reactive oxidative species in a fluid medium containing a source of Cl(I) by irradiating a solid photocatalyst suspended in the fluid medium or residing on a surface that is contactable by the fluid with electromagnetic radiation. The electromagnetic radiation can be in the UV, near-UV, visible, or near-IR consistent with the photocatalyst employed. The source of Cl(I) in certain embodiments is Cl2, HOCl, or H2NCl. The photocatalyst is g-C3N4, TiO2, BBiOBr, or any other solid insoluble photocatalyst.
