Embodiment 1

[0117] A conductive glass substrate (manufactured by Asahi Glass Co., Ltd., 10 Ω / □) having a thickness of 1 mm, a length of 21 mm, and a width of 24 mm having a fluorine-doped tin oxide film was prepared. This fluorine-doped tin oxide film was used as electrode 1 . Polyaniline of 1 μm was deposited on the substrate 1 as the porous body 4 using an electrochemical oxidation method (electrolytic polymerization method). On the other hand, a conductive glass substrate (manufactured by Asahi Glass Co., Ltd., 10Ω / □) having a thickness of 1 mm, a length of 21 mm, and a width of 24 mm having a fluorine-doped tin oxide film was prepared, and the fluorine-doped tin oxide film was sputtered. Platinum is deposited on it, and this is used as the electrode 2. The porous body 4 and the electrode 2 were arranged to face each other, and a hot-melt adhesive (manufactured by Dupont, Bynel) with a width of 1 mm and a thickness of 50 μm was interposed between the outer edge portions thereof. By a...

Embodiment 2

[0119] In Example 2, only the structure of the porous body 4 is different from that of Example 1, and the other structures are the same as those of Example 1.

[0120] The porous body 4 was produced by the following method.

[0121] Electrolytic manganese dioxide (MnO) heat-treated at 400°C 2 , positive electrode active material), acetylene black (conductive agent), polyethylene oxide (viscosity average molecular weight 100,000, manufactured by Sigma-Aldrich Corporation) and LiN (CF 3 SO 2 ) 2 Dissolve or disperse in acetonitrile and mix uniformly to prepare a paste-like positive electrode mixture. Here, to make MnO 2 : Acetylene black: polymer electrolyte = 70% by mass: 20% by mass: 10% by mass. In addition, the mass of the polymer electrolyte is a mass in terms of solid content. The obtained paste-like positive electrode mixture was coated on an electrode, dried at 1200° C. for 24 hours, and then rolled by a roll press to produce a porous body 4 . The carbon dioxide a...

Abstract

An object of the present invention is to provide a carbon dioxide adsorption and release device, which has high adsorptivity, and also consumes low energy upon adsorption and desorption. The carbon dioxide adsorption and release device is characterized by including a pair of electrodes (electrode 1 and electrode 2) provided opposite to each other; an electrolyte 3 filled between the respective electrodes 1 and 2 of the pair of electrodes; and a porous body 4 provided on the electrode 1 of the pair of electrodes, wherein the electrolyte 3 absorbs carbon dioxide thereby dissolving the carbon dioxide therein, and thus enabling formation of carbonic acid ions or hydrogen carbonate ions; and the carbonic acid ions or hydrogen carbonate ions are electrostatically adsorbed on a surface of the porous body 4 when a forward voltage is applied to the pair of electrodes by the porous body 4, and the carbonic acid ions or hydrogen carbonate ions are electrostatically released from a surface of the porous body 4 when a backward voltage is applied to the pair of electrodes.

Description

technical field [0001] The invention relates to a device capable of electrochemically adsorbing and desorbing carbon dioxide. Background technique [0002] Carbon dioxide is a substance that accounts for 0.04% of the atmosphere and is widely present on the earth. It is a compound widely used industrially. Specific examples of industrial utilization of carbon dioxide include foaming gas for carbonated beverages, bath agents, and fire extinguishing agents, dry ice for cooling, and gas for emergency replenishment of bicycles. In addition, carbon dioxide in a supercritical state can be used as an extraction solvent for caffeine, and can also be used as a laser used in industrial processing or a carbon dioxide gas laser used as a medical laser scalpel. In addition, it can also be used as a substitute for Freon-based refrigerants for CO 2 Refrigerant compressors, etc. [0003] In addition, in agriculture, carbon dioxide can be used to promote cultivation of strawberries, carbo...
