Abstract :
The article demonstrates reversible activation upon redox cycling for CH4 oxidation and CO oxidation on Pd supported on high-surface-area LaFeO3, prepared as a thin conformal coating on a porous MgAl2O4 support using atomic layer deposition. The LaFeO3 film, less than 1.5 nm thick, is shown to be initially stable to at least 900 [degrees]C. The activated catalysts exhibit stable catalytic performance for methane oxidation after high-temperature treatment.
