Enhanced ceria nanoflakes using graphene oxide as a sacrificial template for CO oxidation and dry reforming of methane

[Display omitted] •Ceria nanoflakes replicate graphene oxide’s two-dimensional morphology.•Nanoflakes inhibit sintering of both ceria crystallites and deposited Ni particles.•Bare ceria nanoflakes show improved activity for CO oxidation.•Ni-ceria nanoflakes are more stable as a catalyst for dry refo...
