Behavior of Oxygen of Cerium Composite Oxides on Catalytic Combustion of Carbon Particulate
Cerium composite oxide Isotopic oxygen exchange Diesel particulate filter
2009/8/4
Catalyzed diesel particulate filter (CDPF) is an effective way of reducing the carbon particles contained in the emissions of diesel vehicles. The behavior of the oxygen of cerium composite oxides du...
Reduction of MoO3 to Porous Molybdenum Oxides and Its Catalytic Properties for Alkane Isomerization
Molybdenum trioxide Molybdenum hydrogen bronze Hydrogen reduction
2009/7/28
The catalytic activity of partially reduced Pt/MoO3 for alkane isomerization was investigated. The surface area of Pt/MoO3 was markedly enlarged by H2 reduction to a maximum after reduction at 673 K f...

Catalyst-loaded wall-flow type honeycomb is effective for reducing the level of carbon particle emissions from diesel engines. Pt-supported oxides were investigated for the oxidation and reduction of...
Storage and Supply of Pure Hydrogen Mediated by the Redox of Iron Oxides
Hydrogen storage Hydrogen formation Magnetite Iron medium Redox Sintering
2009/7/24
Methods for the storage and supply of pure H2 are proposed based on the reduction of iron oxide with H2 (Fe3O4 + 4H2→3Fe + 4H2O) followed by the oxidation of the iron metal with H2O (3Fe + 4H2O→Fe3O4...
Oxidation of Isobutane over Complex Oxides Containing V and Mg2V2O7 Catalysts Partially Substituted by Transition Metal Ions
Isobutane Oxidation Oxidative dehydrogenation Acidic site
2009/7/24
The oxidation of isobutane was investigated over various complex vanadium oxide catalysts. Mg2V2O7, MgV2O6, and Mg3V2O8 are effective catalysis for isobutene formation at >300°C. Cu2V2O7 and CaV2O6 s...
