Abstract: A photochemical reactor system employing an optical fibers in the form of a cable to transmit light to solid-supported TiO.sub.2 -containing photocatalyst is disclosed. Light energy is transmitted to TiO.sub.2 -containing particles, chemically anchored onto one or more quartz fiber cores, via radial refraction of light out of each fiber. TiO.sub.2 -containing coating layer minimizes the interfacial surface area of the quartz core and TiO.sub.2 -containing particles and operation with incident irradiation angles near 90.degree. enhance light propagation along the fibers. A maximum quantum efficiency of .phi.=1.1% for the oxidation of 4-chlorophenol was achieved. Fiber efficiency permits the light source to be separated from the photocatalyst.

Abstract: A photocatalytic reactor for processing selected reactants from a fluid medium comprising at least one permeable photocatalytic membrane having a photocatalytic material. The material forms an area of chemically active sites when illuminated by light at selected wavelengths. When the fluid medium is passed through the illuminated membrane, the reactants are processed at these sites separating the processed fluid from the unprocessed fluid. A light source is provided and a light transmitting means, including an optical fiber, for transmitting light from the light source to the membrane.

Abstract: The present invention relates to a method for killing cells characterized by bringing a material containing living cells into contact with a non-conductor-carrying photosemiconductor material or a cytocidal material containing the photo semiconductor material and killing the living cells by irradiating light onto the non-conductor-carrying photosemiconductor material, and to a cytocidal agent comprising non-conductor-carrying photosemiconductor material. This non-conductor-carrying photosemiconductor material is relatively inexpensive, since it does not carry a conductor and may be used safely for sterilizing drinking water, food, the human body, and the like because it does not release any poisonous metal ions derived from the conductor in use.

Abstract: A photoreactor including a reservoir configured to hold water, the reservoir defining an inlet and an outlet, and a multiplicity of optical fiber assemblies positioned in the reservoir. Each optical fiber assembly includes one or more optical fibers coated with a composition comprising a photoresponsive polymer and a light source optically coupled to the one or more optical fibers. The photoresponsive polymer undergoes a change from an initial state to an irradiated state when irradiated with light from the light source, and photoresponsive polymer in the irradiated state is adapted to bind an ion from the water.
