Incorporation of noble metals in the low energy surface of ceria can provide enhanced activity for methane activation. Single Pd atoms are stable incorporated in the surface over certain T, PO2 ranges and are more active for C-H dissociation.
Pd-CeO2(111)
CeO2(111) can reconstruct about incorporated Pd to offer the Pd4+, d6 metal a stable octahedral coordination
Pd doped into the CeO2 surface provides a more reducible metal center, enhancing C-H activation
