Synergized PGM catalyst converters configured as three-way catalyst (TWC) systems are disclosed. The disclosed SPGM system configurations exhibit high thermal stability, attenuated air to fuel (A/F) perturbations, enhanced TWC activity, and high catalytic conversion efficiency as a result of synergizing a low PGM loading close-coupled catalyst (CCC), with Ce-based oxygen storage, with a front spinel zone of suitable mixed metal oxide compositions acting as pre-catalyst for oxygen storage. The attenuation of A/F perturbations to lower amplitude, before ex...
1. A catalytic system, comprising: a first catalytic apparatus comprising at least two catalytic portions; anda second catalytic apparatus comprising at least one catalytic portion;wherein one of the at least two catalytic portions of the first catalytic apparatus comprises at least one binary spinel composition and wherein one of the at least two catalytic portions of the first catalytic apparatus comprises a close-coupled catalyst; andwherein the at least one catalytic portion of the second catalytic apparatus comprises a platinum group metal. 2. The c...
