QUANTUM-CHEMICAL CONSIDERATION OF NITROGEN DOPING ON Co3O4 FOR WATER DISSOCIATION

Abstract

We report the results of theoretical investigations of nitrogen doping on Co3O4 (100) bulk by means of the plane-wave periodic density functional theory (DFT) calculations combined with the Hubbard-U approach and statistical thermodynamics. Using accurate DFT+U calculations, we have shown that bulk Co ions denote charges in value 0.017 – 0.57e. For further water adsorption process studies was selected structures with most changes in charges in Co ions: (3) structure for n=25%, (2) structure for n=12.5% and structure for (1) structure.
