IRIDIUM BASED ALLOY CATALYSTS FOR OXYGEN REDUCTION REACTION

摘要

A catalyst comprising an alloy in which two metals are mixed, the alloy comprising iridium (Ir); And silicon (Si), phosphorus (P), germanium (Ge) or As (arsenic); Provided is a catalyst for oxygen reduction reaction, characterized in that the alloy. The catalyst for the oxygen reduction reaction may exhibit a catalytic activity equivalent to or similar to that of a conventional Pt catalyst, but may be very excellent in price competitiveness. Accordingly, it is possible to reduce the amount of platinum catalysts having low price competitiveness, thereby lowering the production cost in the system to which the catalyst is applied.
