Abstract

The interaction of oxygen with preadsorbed hydrogen on thermally activated magnesium oxide has been studied by temperature-programmed desorption (TPD) method. It was found that oxygen at 450 K reacts with preadsorbed hydrogen and the resulting hydroxylation suppresses the adsorptive capacity of magnesia with respect to oxygen.

Abstract

Взаимодействие кислорода с предадсорбированным водородом на термически активированном оксиде магнезия исследовано с помощью метода ТПД. Найдено, что при температуре 450 K кислород реагирует с предадсорбированным водородом, так что результирующее гидроксилирование понижает адсорбционную емкость магнезия по отношению к кислороду.
