Rate enhancing of carbon dioxide in the reaction of acetonitrile with methanol to acrylonitrile over magnesium oxide catalyst
Lin, Yi Wen Ishi, Makoto Ueda, Wataru Morikawa, Yutaka
Carbon dioxide greatly enhanced the formation of acrylonitrile in the gas-phase reaction of acetonitrile with methanol over magnesium oxide catalyst.The reaction in the presence of carbon dioxide was accompanied by the reaction of methanol with carbon dioxide to give carbon monoxide and water.An adsorbed carbon dioxide species on the basic surface of magnesium oxide seems to afford an active methanol-derived species for the reaction with acetonitrile.
Synthesis of MoVNbTe(Sb)Ox composite oxide catalysts via reduction of polyoxometalates in an aqueous medium
Tsuji, Hideto Koyasu, Yukio
The synthesis of MoVNbTe(Sb)Ox composite oxide catalysts based on the self-organization of polyoxometalates (POMs) was investigated. The catalysts which were synthesized via reduction of POMs by using reducing agents under mild conditions and/followed by calcination in an O2-excluded atmosphere which superior performance for propane (amm)oxidation. It was suggested that the metastable phase formed at an elevated temperature with a specific oxidation state corresponds to the catalytic activity. Copyright
