Recyclable Ir Nanoparticles for the Catalytic Hydrogenation of Biomass-Derived Carbonyl Compounds

In situ catalytic hydrogenation of model compounds and biomass-derived phenolic compounds for bio-oil upgrading

The renewable phenolic compounds produced by directional liquefaction of biomass are a mixture of complete fragments decomposed from native lignin. These compounds are unstable and difficult to use directly as biofuel. Here, we report an efficient in situ catalytic hydrogenation method that can convert phenolic compounds into saturated cyclohexanes. The process has high potential for production...

Catalytic Hydrogenation and Oxidation of Biomass- Derived Levulinic Acid

Levulinic acid (LA), 4-oxo-pentanoic acid, is a new platform chemical with various potential uses. In this paper, catalytic hydrogenation and oxidation of levulinic acid were studied. It was shown from experiments that levulinic acid can be hydrogenated to γ-valerolactone (GVL) over transition metal catalysts and oxidative-decarboxylated to 2-butanone (methyl-ethyl-ketone, MEK) and methyl-vinyl...

comparison of catalytic activity of heteropoly compounds in the synthesis of bis(indolyl)alkanes.

heteropoly acids (hpa) and their salts have advantages as catalysts which make them both economically and environmentally attractive, strong br?nsted acidity, exhibiting fast reversible multi-electron redox transformations under rather mild conditions, very high solubility in polar solvents, fairly high thermal stability in the solid states, and efficient oxidizing ability, so that they are imp...

Hydrogenation of Biomass Derived Oxygenates

Microwave-assisted versatile hydrogenation of carbonyl compounds using supported metal nanoparticles.

The efficient microwave-assisted transfer hydrogenation of carbonyl compounds was performed using supported Pt and Pd nanoparticles on Al-SBA-15 materials. Excellent conversions, with exceedingly higher TOF values (4,000-20,000 h(-1)) compared to any previous literature report, were achieved in very short times of reaction (5-30 min), together with complete selectivities to the hydrogenated pro...
