Distinct Crystal‐Facet‐Dependent Behaviors for Single‐Atom Palladium‐On‐Ceria Catalysts: Enhanced Stabilization and Catalytic Properties

High-performance, fully atomically dispersed single-atom catalysts (SACs) are promising candidates for next-generation industrial catalysts. However, it remains a great challenge to avoid the aggregation of isolated atoms into nanoparticles during the preparation and application of SACs. Here, the evolution of Pd species is investigated on different crystal facets of CeO2 , and vastly different behaviors on the single-atomic dispersion of...
