Abstract

Lattice constants in monosize CeO 2-x nanocrystalline particles increase with decreasing particle size. This phenomenon called lattice relaxation is well explained by the model that the number of surface oxygen is reduced to half and its nominal valence is not -2 or -0.5 but -1. This suggests that all the surface oxygen form O 2 2- species in the nanocrystallites.
