Beschreibung
Zusammenfassung:	The present invention relates to catalytic anodes for use in electro-chlorination systems which generate chlorine from aqueous solutions via the chlorine evolution reaction. These anodes comprise an electrically conductive composite metallurgical layer comprising a specific structural base composition to support the catalyst, this base composition essentially comprising ruthenium, tin and titanium, and a specific catalyst composition essentially comprising crystalline cobalt oxide particles. The desired characteristics of this composite metallurgical layer may be realised via a process of preparation employing specific control of reactants and process conditions.
