System and Method for Optimized Oxygen Storage Capacity and Stability of OSM Without Rare Metals

摘要

It is an object of the present disclosure, to provide an oxygen storage material which may include optimum composition and structure of Cu—Mn spinel as OSM, with a suitable doped zirconia, including Niobium-Zirconia support oxide for OSM applications, which may include a chemical composition substantially free from rare metals. The OSC properties of Cu—Mn spinel with a suitable doped zirconia, including Niobium-Zirconia support oxide as OSM may be determined by comparing variations of Cu—Mn composition for determination of the optimum structure of spinel to achieve optimal OSC properties and thermal stability, which may be particularly useful for treating exhaust gases produced by internal combustion engines, where lean/rich fluctuations in operating conditions may produce high variation in exhaust contaminants that may be removed, achieving optimal OSC property of spinel at different temperatures, as well as thermal stability behavior of OSM.
