Thermodesorption of mixtures. Hydrocarbon, hydrogen sulfide and oxygen from the surface of molybdenum sulfide

  • G. A. Komashko

The presence of hydrogen sulfide and oxygen in mixtures increases the number of sites for dissociative desorption on the surface of MoS2 as compared with the adsorption of individual hydrocarbons. This phenomenon can be explained by a change in the coordination state of the active sites (molybdenum ions) upon the adsorption of the gases mentioned.

Установлено, что присутствие в смеси сероводорода и кислорода вызывает увеличение центров деструктивной десорбции на поверхности MoS2 по сравнению с адсорбцией индивидуальных углеводородов. Это явление может быть объяснено изменением координационного состояния активного центраиона молибдена при адсорбции указанных газов.
