Abstract: | Abstract The potential of supported gold catalysts for the selective gas-phase oxidation of methane to methanol with molecular oxygen
was investigated. A broad range of supported gold-based catalyst materials was synthesized using reducible and non-reducible
support materials. Although the formation of small gold nanoparticles was established for all catalyst materials, only a very
low activity for the total oxidation of methane was observed, at temperatures >250 °C. Since no traces of partial oxidation
products, such as methanol, formaldehyde, formic acid, methyl formate, dimethyl ether and CO, were observed it was concluded
that supported gold catalysts are not able to selectively oxidize methane to methanol under these experimental conditions. |
