Abstract: Sodium salt-modified Mn/SiO2 catalysts have been characterized by in situ X-ray diffraction. The results indicate that the low melting point sodium salts exhibit amorphous features under reaction conditions and they are good promoters for the Mn/SiO2 catalyst for the oxidative coupling of methane.

Key words: sodium salt, manganese oxide, silica, in situ X-ray diffraction, low melting point, amorphous, oxidative coupling of methane
