Methanol production apparatus, methanol production method and methanol production electrode

摘要

There has been a demand for a methanol producing apparatus that produces methanol as a reduction product of carbon dioxide without setting it under a special environment. A methanol producing apparatus (10) according to the present disclosure is a methanol producing apparatus (10) that produces methanol by reducing carbon dioxide, comprising a tank (20) for containing an electrolytic solution (17) containing carbon dioxide 11) disposed in the tank (11) so as to be in contact with the electrolytic solution (17), and containing Cu_1-x-yNi_XAu_Y(11) disposed inside the tank (11) so as to be in contact with the electrolytic solution (17) and having a region of a metal or metal compound (0 x, 0 y, x + y 1) And an external power supply (14) for applying a voltage to the cathode electrode (12) so that the cathode electrode (12) is at a negative potential with respect to the potential of the anode electrode (13).
