Title:
VISIBLE-LIGHT-RESPONSIVE POROUS PHOTOCATALYST BODY, METHOD FOR PRODUCING SAME, AND USE OF SAME
Document Type and Number:
WIPO Patent Application WO/2022/172688
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide a novel photocatalyst body which has a porous structure, exerts the activity thereof in a broad light wavelength range including visible light, and has higher oxidative decomposition capability than those of the conventional titanium oxide products. A visible-light-responsive porous photocatalyst body comprising a peroxide of an alkaline earth metal which is consolidated with cement can be produced by an extremely simple process such that a raw material is mixed with water and the resultant mixture is molded and is then dried. The visible-light-responsive porous photocatalyst body exhibits a high photocatalyst activity upon the adsorption of light having a wavelength falling within a broad wavelength range of 200 to 1200 nm. The photocatalyst body can be used in a method for breeding of fish or shellfish or a method for treating a disease in fish or shellfish, a method for preventing the proliferation of a phytoplankton or a pathogenic microorganism or a method for removing a phytoplankton or a pathogenic microorganism, a method for decomposing of a toxic substance or a method for deodorizing a toxic substance, and others.
