Abstract: Chemisorptions of oxygen species on cation site of NiO(100)surface have been studied by means of DV-Xα embedded cluster model calculations, Calculational results show that: i) Adsorption of molecular O2species results in an adsorption state of O22-, which subsequently faciliates the dissociation of the O-O bond to give rise to an O-adspecies; ii)the adsorptions of all the investigated oxygen species increase the oxide state of the cations.

Key words: Oxygen adspecies, NiO(100)surface, Embedded cluster DV-Xα, Adsorption-induced oxidation of cation
