Teaming up main group metals with metallic iron to boost hydrogenation catalysis
Nature Communications, 2022 Elemental iron turns alkaline-earth metal complexes into highly active catalysts for the hydrogenation of alkenes, alkynes, imines and arenes. The proposed mechanism combines homogeneous catalysis by a soluble main group metal hydride complex with ...

Cooperative Dinuclear Activation of a Formate Intermediate in the Hydrogenation of CO2 to Methanol
MoleculesCO2 hydrogenation to methanol is achieved by homogeneous catalysts through a formic acid derivative. Previous studies have focused on using large amounts of additives to activate this intermediate, such as strong acids, amines and alcohols. Hydrogenation

Homogeneously catalysed conversion of aqueous formaldehyde to H2 and carbonate
Nature Communications, 2017 Aqueous formaldehyde is an attractive hydrogen storage system due to the high weight percentage of hydrogen present. Here the authors report a highly active homogeneous ruthenium catalyst system, allowing hydrogen production from formaldehyde-water under

Magnetically Separable Base Catalysts: Heterogeneous Catalysis vs. Quasi-Homogeneous Catalysis
Applied Sciences, 2012 The synthesis of magnetically separable quasi-homogeneous base catalyst and heterogeneous base catalyst is described. The quasi-homogeneous catalyst is achieved by supporting silane monomers functionalized with different amine groups directly on the ...
