Abstract
An exhaust gas purification catalyst contains an oxide 1 and an oxide 2. The catalyst has pores Pwith a pore size of from 1 nm to 260 nm, that can be measured by the nitrogen absorption method, and the total sum ΣPVof the pore volume PVof the pores is equal to or greater than 0.79 cm/g. The oxide 1 is an oxide with an oxygen release capability. The oxide 2 is represented by LaMM'O(2), where M is at least one element selected from the group consisting of Ba, Sr and Ca, M′ is at least one element selected from the group consisting of Fe, Co, Ni and Mn, δ is the amount of oxygen deficiency, x satisfies 0≤x≤1, and δ satisfies 0≤δ≤1.
