摘要： PROBLEM TO BE SOLVED: To provide a method for recovering stain-resisting properties and easy cleanability inherent in a photocatalyst film, by easily removing stain adhered to the photocatalyst film, even when a plasticizer or a fat and oil component contained in a polymeric sealing medium, especially a silicone-based oil contained in the silicone-based sealing medium, effuses to adhere onto the film in a large amount, and the stain caused by the above effluent firmly adheres to the photocatalyst film to deteriorate the stain-resisting properties and easy cleanability inherent in the photocatalyst film. SOLUTION: This method for recovering a photocatalytic action of a photocatalyst film comprises removing stain firmly adhered to the photocatalyst film with a detergent containing at least one kind of compound selected from the group consisting of acids, bases and solvents so recover stain-resisting properties and easy cleanability inherent in the photocatalyst film, when an organic substance comprising semiconductive fine particles or a material containing the semiconductive fine particles adheres firmly to the photocatalyst film to deteriorate the stain-resisting properties and easy cleanability.

摘要： PROBLEM TO BE SOLVED: To obtain a sealing material for building that can reduce the exudation of a plasticizer and a fat or oil component that are included in a polymer sealing material and increase the staining on external finishing materials. SOLUTION: In a sealing material including organic substances 1, for example, a plasticizer, a fat or oil component, particularly a silicone oil-containing silicone sealing material, fine particles of a photocatalyst 3 area allowed to distribute in the material to decompose or degenerate the organic substances, the included plasticizer, fat and oil components, and the like, by the action of the photocatalyst, thereby reducing the staining of buildings due to adhesion of these organic substances to the buildings. The photocatalyst fine particles may be dispersed in the sealing material or may distribute on the surface of the sealing material. Further, a layer including the photocatalyst fine particles may be formed on the sealing material, when necessary, via a layer that inhibits the action of the photocatalyst.

摘要： PROBLEM TO BE SOLVED: To reversibly switch the hydrophilic and hydrophobic properties of the surface of a photocatalytically functional material in accordance with the wavelength of radiated light by combining titanium dioxide with at least one metal selected from the group consisting of Cr, V, Nb, Fe, Cu, Co, Ni and Mn by ion implantation. SOLUTION: Titanium dioxide is combined with at least one specified metal by ion implantation to obtain the objective photocatalytically functional material. The titanium dioxide may be synthesized by CVD, thermo-CVD or sputtering. When the titanium dioxide has a film structure, the film thickness is preferably >=20 nm. Acceleration voltage in the ion implantation is preferably in the range of 50 keV to 2 MeV. A fluorescent lamp, an incandescent lamp or a mercury lamp may be used as a light source for light excitation. The desired wavelength of radiated light is obtained by intercepting the unnecessary wavelength with a color glass filter or the like.

摘要： PROBLEM TO BE SOLVED: To almost inhibit the decomposition and deterioration of a binder by photocatalyst particles and to tightly stick the photocatalyst particles on any substrate over a long period of time without deteriorating the photocatalytic function. SOLUTION: Photocatalyst particles are stuck on a substrate via a hardly decomposable binder, e.g. a silicon compd. such as water glass, colloidal silica or polyorganosiloxane, a phosphate such as zinc phosphate or aluminum phosphate, a biphosphate, an inorg. binder such as cement or an org. binder such as a fluorine- or silicon-contg. polymer. The amt. of the photocatalyst particles is 5-98 vol.% of the total amt. of the particles and the hardly decomposable binder.

摘要： PROBLEM TO BE SOLVED: To' successively use a photocatalyst in photochemical reaction treatment without discharging it and deteriorating the result of the treatment by regenerating the photocatalyst, which is used in the photochemical reaction treatment of the org. matter, etc., in a liq. and begins to lower in activity due to the deposition of the hardness component, with an acid soln., etc. SOLUTION: The photoirradiation by a mercury lamp, etc., is conducted in the presence of a photocatalyst to photochemically oxidize and decompose the org. matter in a liq. The photocatalyst with the activity remarkably lowered due to the hardness component such as calcium in the liq. is cleaned with an acid soln., etc., to remove the hardness component. The point of time immediately before the photocatalyst is lowered in activity due to the deposition of the hardness component in the liq. is recognized by the point of time when the ratio of the metallic atom of the photocatalyst to the atom of the hardness component depositing on the catalyst becomes 1 to 100:100 to 1, the photocatalyst is cleaned with an acid soln. (bubbling) to remove the hardness component, and the photocatalyst is regenerated accurately and effectively.

摘要： PROBLEM TO BE SOLVED: To provide production by which a photocatalyst layer that shows good covering power and excellent adhesion even to an aluminum alloy base material having a complicated shape, can be formed without reducing strength of the aluminum alloy base material. SOLUTION: This production comprises: subjecting a base material 11 that consists of an aluminum alloy, to anodic oxidation treatment to form an anodic oxide coating film 12 on the base material 11; further immersing the treated material in a solution contg. suspended fine semiconductor particles 10, coating the treated material with the solution contg. suspended fine semiconductor particles 10 (liquid suspension of fine semiconductor particles 10) or subjecting the treated base material to electrophoresis treatment in the liquid suspension of fine semiconductor particles 10, to deposit the fine semiconductor particles 10 on the anodic oxide coating film 12; and thereafter, subjecting the resulting material to sealing treatment to form a photocatalyst layer consisting of a composite phase in which a swelled anodic oxide coating film 12a and the fine semiconductor particles 10 coexist, and also to improve corrosion resistance of the aluminum alloy base material 11. At this time, since the production is a wet process, the photocatalyst layer that shows good covering power even to the base material having a complicated shape, can be formed even at room temp. Thus, the formation of the photocatalyst layer also having sufficient massproductivity can be performed without any possibility of reducing strength of the aluminum alloy base material 11.
