Zur LanganzeigeZusammenfassung
We report the results of theoretical investigations of nitrogen doping on Co 3 O 4 (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 forn = 12.5% and structure for (1) structure.
