Abstract
A cathode catalyst used for conversion of a carbon dioxide gas by an electrochemical reduction includes at least one first catalyst layer and at least one second catalyst layer disposed on a surface of the at least one first catalyst layer. The at least one second catalyst layer is a porous structure. The at least one first catalyst layer and the at least one second catalyst layer are physically combined with each other, and materials of the at least one first catalyst layer and the at least one second catalyst layer are different. A cathode material and a reactor include the cathode catalyst are also provided.
