1. A carbon dioxide adsorption-desorption device comprising an electrode, the electrode comprising a porous composite, the porous composite comprising:
an electro-conductive component; and
a porous material covering the electro-conductive component with a thickness of 1 nm or more and 5 nm or less, the porous material having pores of an angstrom size or a nanometer size, and comprising a moiety exhibiting redox activity according to electrical response,
wherein the porous composite is obtained by covering the surface of the electro-conductive component with the porous material,
wherein the electro-conductive component is not covered with a porous material having a thickness of greater than 5 nm, and
the porous material comprises a metal-organic framework with electrical activity, the metal-organic framework having a UiO structure, a Cu (2,7-anthraquinone dicarboxylic acid) structure, or a Mn (2,7-anthraquinone dicarboxylic acid) structure.
