The present invention relates to the electrolytic splitting of water using a carbon-supported manganese oxide (MnO) composite. Specifically, the present electrolytic splitting of water is carried under neutral electrolyte conditions with a high electrolytic activity, while using an oxygen evolution reaction (OER)-electrode comprising the present carbon-supported MnOcomposite. Next, the present invention relates to a process for producing such a carbon-supported MnOcomposite as well as to a composite obtainable by the present process for producing the same and to an OER-electrode comprising the carbon-supported MnOcomposite obtainable by the present process.
