Ground-state diagrams for lattice-gas models of catalytic CO oxidation
Based on simple lattice models of catalytic carbon dioxide synthesis from oxygen and carbon monoxide, phase diagrams are investigated at temperature T = 0 by incorporating the nearest-neighbor interactions on a catalyst surface. The main types of ground-state phase diagrams of two lattice models a...

Digital Library of Periodicals of National Academy of Sciences of Ukraine| Zusammenfassung: | Based on simple lattice models of catalytic carbon dioxide synthesis from oxygen and carbon monoxide,
phase diagrams are investigated at temperature T = 0 by incorporating the nearest-neighbor interactions
on a catalyst surface. The main types of ground-state phase diagrams of two lattice models are classified
describing the cases of clean surface and surface containing impurities. Nonuniform phases are obtained and
the conditions of their existence dependent on the interaction parameters are established.
В рамках простих ґраткових моделей каталiтичного синтезу вуглекислого газу з кисню та чадного газу дослiджуються фазовi дiаграми при температурi T = 0 iз врахуванням взаємодiй на поверхнi мiж найближчими сусiдами. Прокласифiковано основнi типи фазових дiаграм основного стану для моделей без домiшок та у випадку присутностi домiшок. Знайдено умови iснування неоднорiдних областей залежно вiд значень параметрiв взаємодiї.
