Ruthenium-Catalyzed Hydrogenation of Bicarbonate in Water

Hydrogenation of bicarbonates in water: By using a ruthenium-based catalytic system hydrogenation of sodium bicarbonate was achieved in water in comparable high TONs and yields. The hydrogenation of sodium bicarbonate takes place with the catalytic system ...

Imaging and characterization of activated CO2 species on Ni(110)

Alfonso Baldereschi, Michele Rizzi

By means of a joint experimental and theoretical approach we provide single molecule imaging and characterization of CO2 on Ni(110), chemisorbed with high charge transfer from the substrate in an activated state that plays a crucial role in the hydrogenati ...

Nitrogen fixation at passivated Fe nanoclusters supported by an oxide surface: Identification of viable reaction routes using density functional calculations

Alfredo Pasquarello, Harald Brune, Zeljko Sljivancanin

Using density-functional calculations, we investigate the possibility of ammonia synthesis at supported Fe nanoclusters along catalytic routes closely resembling those in biological nitrogen fixation. To achieve similar catalytic conditions as at the activ ...

Novel catalytic applications of carbon nanofibers on sintered metal fibers filters as structured supports

Marina Ruta

Supported metal catalysts are important from both an industrial and a scientific point of view. They are used, amongst others, in large-scale processes such as catalytic reforming, hydrotreating, polymerization reactions and hydrogenations. Often, these ca ...

Homogeneous catalytic decomposition of formic acid for high pressure hydrogen generation

Céline Fellay

The main obstacles in the widespread use of hydrogen as energetic alternative to fossil fuels are storage problems intrinsically linked to its extremely light and explosive nature. Since no ideal storage systems currently exist, reversible fixation of hydr ...
