Carbon dioxide reduction catalyst device, carbon dioxide reduction method and method for producing catalyst

Abstract

The present invention addresses the problem of providing a carbon dioxide reduction catalyst device which is capable of favorably producing a hydrocarbon having 8 to 16 carbon atoms by a hydrogenation reaction of carbon dioxide. In order to solve the problem, the present invention provides a carbon dioxide reduction catalyst device which produces a hydrocarbon by causing a hydrogenation reaction of carbon dioxide and reducing the carbon dioxide, and which comprises a first catalyst that contains, as catalyst metals, Fe and at least one of Ga and Zr, and a second catalyst that contains, as catalyst metals, Fe and Co. With respect to this carbon dioxide reduction catalyst device, the second catalyst is disposed in the downstream of the first catalyst.
