indicating the preferential growth on Pt (111) facet. This facet-selective coating
structure exposed Pt active facets and formed Pt-CeO 2 interfaces at the same time
which were helpful for activity enhancement toward CO oxidation. The CeO 2 -coated
catalyst was also stable under calcination at 700 °C due to the physical confinement
effect of the coating layer that suppressed NPs migration.
