Mechanisms and controlling characteristics of the oxidation of methane. Progress report
The research aims at the scientific foundations for processes dealing with selective oxidation of methane to methanol and formaldehyde. Progress has been achieved in two major areas: (a) Catalytic oxidation of methane to formaldehyde by molecular oxygen over molybdena-based catalysts at subatmospheric pressures; the catalysts have been characterized by laser Raman microprobe, electron microscopy, EPR, and ESCA/Auger spectroscopy; (b) Surface science of adsorbates in the palladium-oxygen-dichloromethane-methane system. A combined LEED/Auger/Mass Spectrometer apparatus dedicated to this project has been constructed and is in operation. The structures, energetics, and desorption patterns of oxygen and dichloromethane overlayers have been determined on the Pd(100) crystal surface. An interesting exclusion of dichloromethane chemisorption by preadsorbed oxygen and the occurrence of oxygen chemisorption into the dichloromethane overlayer indicate a reaction pattern that will be very sensitive to the gas phase oxygen-to-dichloromethane concentration ratio.
