Abstract
An electrode for treating hard-dissoluble waste water requires high oxygen overvoltage, lowerprice and durability. Conventional electrode can not satisfy all of the above three conditions. The present invention provides an elelctrode capable of satisfying all of the above conditions comprising of novel substrate and novel electrode catalyst. The novel electrode catalyst is a three-element catalyst composed of the oxides of Sn--Pt--Ru, and the novel substrate is a ceramic Ti4O7. Such system satisfies durability, cost and electrode voltage characteristics.
