PRODUCTION OF REACTIVE OXIDATIVE SPECIES BY PHOTOCATALYTIC ACTIVATION OF CHLORINE (I) UNDER ULTRAVIOLET/VISIBLE LIGHT/NEAR INFRARED IRRADIATION

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.
