Mossbauer Effect Spectra of Ammonia Adsorption on a Supported Iron Catalyst

Naturevolume 214pages7980 (1967) | Download Citation



THE Mossbauer effect has been used to obtain structural information on ferric oxide supported on silica and on alumina1–3; the experimental conditions under which these studies were carried out did not, however, allow observations on chemisorption or reduction of the catalysts. This communication reports some initial work applying the Mossbauer effect to a study of supported iron catalysts which have been reduced with hydrogen.
