Formation, Stability, and Reactivity of atomically dispersed transition metals stabilized on oxide supports
EMSL Project ID
44740
Abstract
In the course of our previous studies, we learned that the support may be modified during reaction especially after elevated temperature treatments due to the incorporation of atomically dispersed transition metals. Aberration corrected STEM (AC-STEM) in conjunction with EXAFS provides convincing evidence of the presence of atomically dispersed Pd atoms on the ZnO and also on La-stabilized. The proposed work will focus on the formation, stability and reactivity of these atomically dispersed transition metal species. They constitute a novel form of metal-support interaction where the metal provides atoms get anchored on a support and modify its catalytic behavior. And the results show that these species are stable at elevated temperatures, so they may play a significant role in the overall catalytic reactivity.
