Tune the oxygen storage properties of Ca₂MnAlO_5+δthrough chemical doping

摘要

An oxygen storage material including a compound of the formula: Ca₂MnAlO_5+δ wherein 0≦δ≦0.5 wherein the compound includes at least one dopant said dopant selected from alkaline earth ions at the Ca site, trivalent ions at the Al site, and 3d transition metal ions at the Mn site wherein the an oxygen release temperature or an oxygen storage temperature is modified in comparison to an un-doped Ca₂MnAlO_5+δ material.
