Тип записи:Публикация, Theoretical investigations of nitrogen doping on Co3O4for water dissociation catalytically activity(IOP Publishing, 2018-11-01); ;Yuri A. Mastrikov ;Eugene A. Kotomin; 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.Цитирования (OpenAlex) 1 - Некоторые метрики заблокированы вашиминастройками согласия
Тип записи:Публикация, First-Principles Modelling of N-Doped Co 3 O 4Abstract N-doped Co 3 O 4 is a promising electrocatalyst. By means of first-principles calculations, various concentrations and spatial arrangements of N O atoms were modelled. Mutual interaction of the dopant atoms was analysed with respect to single N O atom. Charge redistribution, caused by doping, was calculated.Цитирования (OpenAlex) 1Цитирования (OpenCitations) 1 - Некоторые метрики заблокированы вашиминастройками согласия

Тип записи:Публикация, Oxygen Evolution Reaction on a N-Doped Co 0.5 -Terminated Co 3 o 4 (001) Surface(De Gruyter Open, 2020-12-01); ; ;Талгат Муратович Инербаев ;Yuri A. MastrikovEugene A. KotominAbstract Recent experimental findings suggest that the catalytic activity of Co 3 O 4 for oxygen evolution reaction (OER) could be improved by nitrogen doping. We present preliminary OER modelling on a N-doped Co 3 O 4 surface, with varying concentration of the dopant and its spatial distribution around Co oct and Co tet adsorption sites. The overpotential was calculated for two adsorption sites on seven types of N-doped Co 3 O 4 surface. The largest calculated overpotential value for a N-doped surface was ~1V.Цитирования (OpenAlex) 1 - Некоторые метрики заблокированы вашиминастройками согласия
