TL;DR: Gold nanoparticles on a number of supporting materials, including anatase TiO2 (TiO2-A, in 40 nm and 45 μm), rutile TiO 2 (R), ZrO2, Al2O3, SiO2, and activated carbon, were evaluated for hydrodeoxygenation of guaiacol in 6.5 MPa initial H2 pressure at 300 °C as discussed by the authors.

TL;DR: In this article, a biphasic system containing glycol dimethyl ether (GDE) as the extraction phase, and [BMIM]Cl/CrCl3/glucose in combination with a partitioned amount of GDE and an appropriate amount of water as the reaction phase was found to be highly efficient for the reaction; CrCl3 catalyzed the formation of 5-HMF in 64.5 mol% yield from a very high glucose concentration (80 wt% with respect to the ionic liquid) at 108 °C.

TL;DR: In this paper, a sub-nanometer sized silver, a poor hydrogenation metal catalyst, was found to initiate H2 dissociation and H spillover onto anatase TiO2 (TiO2-A) surface.

TL;DR: In this article, the complex dichlorobis(2,9-dimethyl-1,10-phenanthroline)ruthenium(II) (Ru(DMP)2Cl2) was found to effectively catalyze the direct reductive amination of bio-based 5-hydroxymethylfurfural (5-HMF) in the presence of H2 (g) in ethanol solvent.

TL;DR: In this paper, the mechanism of humin formation in glucose/fructose conversion to HMF was studied in an ionic liquid system (1-butyl-3methylimidazolium chloride, [BMIM]Cl) with CrCl3 as the catalyst.
