Oxidation of methane and ethylene in water at ambient conditions
Sorokin Kudrik Alvarez Afanasiev Millet Bouchu
Available spectroscopic, labelling and reactivity data show that stable μ-nitrido diiron phthalocyanine activates H2O2 to form a high-valent diiron oxo species. This species is a very powerful oxidant which oxidizes methane in pure water at 25-60 °C to methanol, formaldehyde and formic acid. The catalytic activity can significantly be increased in the presence of a diluted acid solution. Thus, a high turnover number of 209 was attained in 0.075 M H2SO4. Oxidation of ethylene resulted in the formation of formic acid as a major product and formaldehyde with high turnover numbers. Under optimal conditions, 426 mol HCOOH and 37 mol CH 2O per mole of catalyst were obtained in pure water. The practical and green features of this novel approach (H2O2 as the clean oxidant, water as the clean reaction medium, easily accessible solid catalyst) as well as the relevance to biological oxidation (binuclear structure of bio-inspired complex) are of great importance both from practical and fundamental points of view.
Partial Oxidation of Methane by Nitrous Oxide over Molybdenum Oxide supported on Silica
Liu, R.-S. Iwamoto, M. Lunsford, Jack H.
Methanol and formaldehyde were formed as major products at a moderate conversion level (16percent) in the partial oxidation of methane by nitrous oxide in the presence of water over molybdenum oxide supported on silica.
