1. A structured catalyst for CO shift or reverse shift, comprising:
a support of a porous structure composed of a zeolite-type compound; and
at least one CO shift or reverse shift catalytic substance present in the support, wherein
the support has channels connecting with each other, and
the CO shift or reverse shift catalytic substance is present at least in the channels of the support,
wherein
the channels have any one of a one-dimensional pore, a two-dimensional pore, and a three-dimensional pore defined by a framework of the zeolite-type compound and an enlarged pore portion different from any of the one-dimensional pore, the two-dimensional pore, and the three-dimensional pore,
the CO shift or reverse shift catalytic substance is present at least in the enlarged pore portion,
a diameter of CO shift or reverse shift catalytic substance is greater than a pore diameter of the zeolite-type compound, and
the enlarged pore portion is a new skeletal structure providing support for the structured catalyst for CO shift or reverse shift.

15. A method of producing carbon monoxide and water, the method comprising:
reacting carbon dioxide and hydrogen using a catalyst to generate carbon monoxide and water using a reverse shift reaction,
wherein
the catalyst comprising:
a support of a porous structure composed of a zeolite-type compound; and
at least one type of metal nanoparticles present in the support, wherein
the support has channels connecting with each other,
the metal nanoparticles include a structured catalyst for reverse shift present in at least an enlarged pore portion of the channels, a diameter of the metal nanoparticles are greater than a pore diameter of the zeolite-type compound, wherein the enlarged pore portion is a new skeletal structure providing support for the structured catalyst for CO shift or reverse shift.
