    Magnesia–Carbon Nanotubes (MgO–CNTs) Nanocomposite: Novel Support of Ru Catalyst for the Generation of COx-Free Hydrogen from Ammonia

    Magnesia–carbon nanotubes (abbreviated as MgO–CNTs) nanocomposites were prepared by impregnation of CNTs with Mg(NO3)2·6H2O in ethanol solution, followed by drying at 353 K and calcination at 873 K, respectively....

    Catalytic Production of Carbon Nanotubes by Decomposition of CH4 over the Pre-reduced Catalysts LaNiO3, La4Ni3O10, La3Ni2O7 and La2NiO4

    A large amount of more graphitic carbon nanotubes with a narrow size distribution was produced from catalytic decomposition of CH4 over pre-reduced LaNiO3, La4Ni3O10, La3Ni2O7 and La2NiO4. The structure and compo...

    Mechanistic studies of CO2/CH4 reforming over Ni–La2O2/5A

    The mechanism of CO2/CH4 reforming over Ni–La2O3/5A has been studied. The results of the CO2‐pulsing experiments indicated that the amount of CO2 converted was roughly proportional to the amount of H present on t...

    An ab initio study of methane activation on lanthanide oxide

    Ab initio MP2 calculations have been carried out to study the activation of methane on lanthanide oxide La2O3. O- and O2 2- are assumed to be the active species on the oxide surface. The p...

    Oxidative coupling of methane over LaF3/La2O3 catalysts

    We studied the oxidative coupling of methane over the LaF3/La2O3 (50∶50) catalyst. The catalyst was found active even at 873 K. At 1023 K, the C2 yield was 12.7% at 26.0% CH4 conversion and 49.1% C2 selectivity. ...
