Method of manufacturing acetic acid

Abstract

A method of manufacturing acetic acid by reducing carbon dioxide from the atmosphere includes: a step of carrying out a treatment of immersing a hydrogen storage alloy negative electrode, which is used in a nickel-hydrogen battery, in an alkaline electrolytic solution and thereafter drying the negative electrode; and a step of, by using an electrolysis cell having an alkaline electrolytic solution that can adsorb carbon dioxide, a positive electrode that is used in a nickel-hydrogen battery, the hydrogen storage alloy negative electrode after the treatment, and a power source connected to the positive electrode and the negative electrode, reducing the carbon dioxide by applying, to the positive electrode and the negative electrode, a potential difference such that a potential of the positive electrode becomes higher than a potential of the negative electrode, wherein the alkaline electrolytic solution of the electrolysis cell is a K2CO3 aqueous solution.
