Abstract: Mössbauer spectroscopy has been utilized for studying the action of Mg element in iron oxide catalysts used for the dehydrogenation of ethylbenzene to styrene. The experimental results show that the presence of opportune amount of Mg can enhance the stability and dispersion of catalysts, i.e. Mg is an useful structure promoter in this kind of catalysts.
