Atomic cerium modulated palladium nanoclusters exsolved ferrite catalysts for lean methane conversion.

ABSTRACT: The active and stable palladium (Pd) based catalysts for CH₄ conversion are of great environmental and industrial significance. Herein, we employed N₂ as an optimal activation agent to develop a Pd nanocluster exsolved Ce-incorporated perovskite ferrite catalyst toward lean methane oxidation. Replacing the traditional initiator of H₂, the N₂ was found as an effective driving force to selectively touch off the surface exsolution of Pd nanocluster from perovskite framework without deteriorating the overall material robustness. The catalyst showed an outstanding T₅₀ (temperature of 50% conversion) plummeting down to 350°C, outperforming the pristine and H₂-activated counterparts. Further, the combined theoretical and experiment
