Abstract

The variation of MgO surfaces, in which fluorine was contained (F-MgO), by high energy electron-beam (EB) was studied using X-ray photoelectron spectroscopy (XPS). Fluorine on the MgO surface was eliminated by EB treatment with the consequence that the electronic structures of Mg, O and C were varied. Moreover, as a result of oxidation of carbon species on the surface by high dose EB treatment (90 kGy), the concentration of carbonate and carboxyl species on the surface was increased. In this experiment, it was confirmed that the structure of oxidized metal surface can be adjusted by varying conditions of EB treatment (energy and dose). This result implies that EB can be applied for developing new catalysts.
