Abstract—The nature of the alumina surface irradiated with electrons active in methanol dehydration was stud-
ied by exoemission in comparison with the initial surface. Methanol decomposition and thermal treatment in a
vacuum were found to influence the formation of the active surface of the catalyst. Methanol dehydration
occurred on centers formed with the participation of low-coordinate surface oxygen, O^–, which represented
exoemission centers. The desorption of methanol and its decomposition products was accompanied by the
emission of negative charges. A possible reaction mechanism is discussed.
