The present invention provides a method for efficiently generating oxygen by electrolysis of water using a copper delafossite compound as an anode. The present invention is a method for generating oxygen, comprising the following steps: (a) preparing a water electrolyzer comprising: a container 11, a power supply 14, an anode 12, The cathode 13 and the aqueous electrolyte solution 15, where the anode 12 and the cathode 13 are in contact with the aqueous electrolyte solution 15, and the anode 12 has a copper cobalt delafossite compound represented by the chemical formula CuCoO 2. The cobalt delafossite compound is in contact with the electrolyte aqueous solution 15, and (b) electrolysis of water generated on the copper cobalt delafossite compound by applying a potential difference between the cathode 13 and the anode 12 using the power source 14. Generating oxygen on the anode 12 via the step. [Selection] Figure 1 |
