ABSTRACT:
A water chlorinator includes an aqueous chloride ion source; and a pair of dual functional electrodes configured to electrolyze the aqueous chloride ion source, each one of the pair of dual functional electrodes comprising a titanium substrate and a mixed metal oxide coating deposited thereon and consisting essentially of ruthenium oxide and titanium oxide having a molar ratio of 5:95 to 25:75, respectively.
