Synthesis for Materials for Reversible Uptake and Useful Functionalization of Methane. Annual Report January-December 1988

摘要

The report describes such programs in chemistry designed to discover new materials that will reversibly absorb methane gas, or that will act as catalysts for the selective conversion of methane to useful products such as carbon monoxide and dihydrogen, methanol, formaldehyde or ethylene. Heterogeneous catalysts for selective oxidative coupling of methane to ethylene giving ethylene and ethane are described. Compounds of general formula Ln2Sn2O7, where Ln represents the lanthanide elements, are for some of the elements moderately selective towards the formation of ethylene in up to 10% yield. The synthesis of organo-transition metal-intercalation compounds of metal oxides where the metal oxides where the metal oxide lattice is, for example, molybdenum trioxide have been prepared.
