METHOD FOR GENERATING OXYGEN AND WATER ELECTROLYSIS DEVICE

摘要

The present invention provides a method for efficiently generating oxygen by electrolyzing water using a copper delafossite compound as an anode. First, in the present invention, a water electrolysis device is prepared. The water electrolysis device comprises a container, a power supply, an anode, a cathode; and an aqueous electrolytic solution. The anode and the cathode are in contact with the aqueous electrolytic solution. The anode has a copper cobalt delafossite compound represented by a chemical formula CuCoO2. The copper cobalt delafossite compound is in contact with the aqueous electrolytic solution. Then, an electric potential difference is applied between the cathode and the anode using the power supply to generate oxygen on the anode due to electrolysis of water which occurs on the copper cobalt delafossite compound.
