Abstract

The nature of the dynamic active centers formed by the surface reduction of MoO3 catalysts calcined at 700°C, has been investigated. CO, H2 and H2O pulses result in a temporary increase of the activity of this catalyst. Mo5+−OH doublets seem to be new active sites for the double bond shift.

Abstract

Изучена природа динамических активных центров, образующихся при поверхностном восстановлении MoO3 катализатора, прокаленного при 700°C. Добавки CO, H2 и H2O временно увеличивают активность катализатора. Дуплеты Mo5+−OH являются, по-видимому, новыми активными частицами миграции двойной связи.
