Transformation of bulk Pd to Pd cations in small-pore CHA zeolites facilitated by NO
Atomic dispersion of metal species has attracted attention as a unique phenomenon that
affects adsorption properties and catalytic activities and that can be used to design so-called
single atom materials. In this work, we describe atomic dispersion of bulk Pd into small pores
of CHA zeolites. Under 4% NO flow at 600° C, bulk Pd metal on the outside of CHA zeolites
effectively disperses, affording Pd2+ cations on Al sites with concomitant formation of N2O,
as revealed by microscopic and spectroscopic characterizations combined with mass …
