PROBLEM TO BE SOLVED: To use a Cu-Sn-P alloy as a working electrode for producing, with high current efficiency, hydrocarbon gases relatively insoluble in aqueous solution, such as methane and ethylene, as substitutes for petroleum in electrochemical reduction of carbon dioxides. SOLUTION: For the purpose of producing hydrocarbon gases relatively insoluble in aqueous solution, such as methane and ethylene, with high current efficiency in the electrochemical reduction of carbon dioxides, it is necessary to allow the adsorption of CO to occur simultaneously with the generation of hydrogen by water electrolysis on an electrode used. In order to solve this problem, copper is alloyed with heteroatoms to change the surface energy of the electrode and control the CO adsorption and the hydrogen generation by water electrolysis.
