摘要：

An iron sodalite catalyst similar to that reported to have good selectivity for the oxidation of methane to methanol by Lyons et al. has been prepared, tested and characterised. In a limited range of temperature at 34 bar total pressure the selectivity of the catalyst to methanol is a little better than that of an empty silica glass reactor. Before reaction, X-ray powder diffraction and Mossbauer spectroscopy confirm the presence of Fe(III) in the sodalite framework. After reaction Mossbauer spectroscopy identifies Fe(II) and also small particles of iron(Ill) oxide, < 1 mu m in size.
