Abstract:
A reduction catalyst body for carbon dioxide of an embodiment includes a metal layer, and a projection provided on the metal layer. The projection is constituted of an aggregate of fine metal particles, and possesses a polyhedral structure having surfaces of three faces or more of a polygon. The projection has a site of reducing carbon dioxide, as at least a part of the surfaces.
