Synthesis and characterization of nickel-doped ceria nanoparticles with improved surface reducibility

Nickel-doped ceria nanoparticles (Ni(0.1)Ce(0.9)O(2−x) NPs) were fabricated from Schiff-base complexes and characterized by various microscopic and spectroscopic methods. Clear evidence is provided for incorporation of nickel ions in the ceria lattice in the form of Ni(3+) species which is considere...

description Nickel-doped ceria nanoparticles (Ni(0.1)Ce(0.9)O(2−x) NPs) were fabricated from Schiff-base complexes and characterized by various microscopic and spectroscopic methods. Clear evidence is provided for incorporation of nickel ions in the ceria lattice in the form of Ni(3+) species which is considered as the hole trapped state of Ni(2+). The Ni(0.1)Ce(0.9)O(2−x) NPs exhibit enhanced reducibility in H(2) as compared to conventional ceria-supported Ni particles, while in O(2) the dopant nickel cations are oxidized at higher valence than the supported ones.
