Abstract: A gas phase reduction device for carbon dioxide is a gas phase reduction device for carbon dioxide that exerts a catalytic function by light irradiation to generate oxidation-reduction reaction. The gas phase reduction device includes an oxidation tank in which an aqueous solution is put, a reduction tank to which carbon dioxide is supplied, a semiconductor photoelectrode installed in the aqueous solution, and a porous electrode-supported electrolyte membrane that is a joint body of an electrolyte membrane and a porous reduction electrode, the porous electrode-supported electrolyte membrane being installed between the oxidation tank and the reduction tank with the electrolyte membrane facing the oxidation tank and the porous reduction electrode facing the reduction tank.

Abstract: A clip may include an anchor portion, an elastic engagement strip and two ribs. The engagement strip is formed in a portion adjacent to a distal end of the anchor portion and is extended vertically therefrom toward a proximal end of the anchor portion. The two ribs are formed in an outer surface of the engagement strip and are vertically spaced from each other. The ribs are formed such that the rib that is away from the distal end of the anchor portion has a projection amount smaller than the rib that is close to the distal end of the anchor portion.
