Seawater can be used as an electrolyte for Cl2 evolution, and proper selection of electrode materials is of great importance. In this paper, a new type of dimensionally stable anodes, Ti/RuO2-IrO2-Sb2O5-SnO2, was investigated for Cl2 evolution from seawater. The physicochemical and electrochemical properties were examined, and the electrocatalytic activity for Cl2 evolution was measured under different conditions. It was shown that the RuO2-IrO2-Sb2O5-SnO2 coating was compact in microstructure. The current efficiency was 71.2–86.7%, depending on the operational conditions. The anodes were predicted to be able to work effectively for over 6 years at a current density of 1500 A m−2 for seawater electrolysis.
