Provided is a method for manufacturing a titania coated alumina fiber aggregate which includes the steps of: forming an aluminum fiber aggregate where aluminum fibers are aggregated with density per unit volume of 0.5 g/cmto 3 g/cm; forming an alumina fiber aggregate where an oxide film having a film thickness of 50 nm or more is formed on alumina fibers; and forming a titania coated alumina fiber aggregate where a titania thin film is formed on alumina fibers.

Method for manufacturing titania coated alumina fiber aggregate

The present invention provides an apparatus for producing water having redox activity. In the apparatus, at least one of oxygen, ozone, chlorine, nitrogen monoxide, and ammonia as a reaction precursor is previously mixed into water or running water while regulating the concentration of the dissolved substance followed by the application of ultrasonic vibrations, whereby active oxygen species are generated in water. In another embodiment, water or running water is brought into contact with a catalyst to which ultrasonic vibrations or electromagnetic waves have been applied, whereby active oxygen species are generated in water.

Apparatus for producing water having redox activity

The present invention provides an apparatus for producing photocatalytic reaction water through a photocatalytic reaction, which can produce water containing a satisfactory amount of active oxygen species, can eliminate microorganisms, parasites or protozoa, shows high oxidizing ability for a prolonged period of time, can reduce the power requirements, is small in size, and is applicable to various devices. A photocatalyst is radiated with light emitted from a light source to produce active oxygen species, and the active oxygen species is diffused in water, whereby the water is provided with functions of the active oxygen species. An oxidation reaction with the water is utilized to perform at least one selected from the elimination of microorganisms, the elimination of parasites, and the elimination of protozoa.
