DIMENSIONALLY STABLE ELECTRODE FOR TREATING HARD-RESOLUBLE WASTE WATER

摘要

An electrode for treating hard-dissoluble waste water requires high oxygen overvoltage, lower price and durability. Conventional electrode can not satisfy all of the above three conditions. The present invention provides an electrode 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 Ti407. Such system satisfies durability, cost and electrode voltage characteristics.
