CH4 and NOx conversion data show that the dual-layer catalyst outperforms single-layer samples having the same catalyst loadings, with and without spinel. Close proximity of the PGM and MFO functions in the mixed-layer catalyst lowers the CH4 conversion at high temperature while separating the PGM and spinel layers with an intermediate Al2O3 layer does not. Methane conversion enhancement is linked to its nonmonotonic dependence on O2. The performance gains are tied to a transient activity spike that occurs during the lean-to-rich feed transition when water is present in the feed. The transient spike is attributed to the removal of CO and H2 products via reactions with stored O2 in the spinel, eliminating inhibition of methane steam reforming.

We demonstrate the possible formation of three distinct phases based on the magnetization energy calculated self-consistently for the ferromagnetic MEFM and antiferromagnetic MEAFM states, i.e., the paramagnetic phase with MEFM=MEAFM, the ferromagnetic phase with MEFM MEAFM, and finally the polarized itinerant electrons with finite MEFM but zero MEAFM. While the ON system was found to exist in all three phases, no tendency toward the formation of the polarized itinerant electrons was observed for the SiB system though the existence of the other two phases was ascertained. The different behavior of these two systems is associated with the diverse features in the magnetization energy as a function of the oxygen and silicon concentration...
