“…Its catalytic performance was similar to that of Rh NPs on TiO 2 -coated SiO 2 , showing either that coverage of the NPs themselves was irrelevant for catalysis, or that the system was dynamic and reached the same (SMSI) state during catalysis. The latter option can be rationalized considering that overlayer deposition can be used to create artificial support suboxide coverage on NPs, thereby mimicking an SMSI state 141 .…”

“…Metal particles on reducible supports have shown promising results in HMF transformation to DMF [39] . One interesting future direction would be to study atomic layer epitaxy method to develop catalysts with small metal particles on reducible supports as discussed in the literature [93] . Although this method is not novel, [94] it still attracts attention in developing catalysts for selective hydrogenation/hydrogenolysis reactions.…”

“…[39] One interesting future direction would be to study atomic layer epitaxy method to develop catalysts with small metal particles on reducible supports as discussed in the literature. [93] Although this method is not novel, [94] it still attracts attention in developing catalysts for selective hydrogenation/ hydrogenolysis reactions. The deep knowledge regarding the balance between acid and metal sites is scarce and these topics have only been studied in a few works.…”

Catalytic Hydrogenation/Hydrogenolysis of 5‐Hydroxymethylfurfural to 2,5‐Dimethylfuran

Recent developments in transformations of biobased 5hydroxymethylfurfural to 2,5-dimethylfuran, a potential liquid fuel, are critically summarized. The highest yield of 2,5-dimethylfuran (more than 98 %) from 5-hydroxymethylfurfural are obtained over bimetallic CuÀ Co supported on carbon at 180°C under 5 bar hydrogen in 2-propanol and over Ni supported on mesoporous carbon at 200°C under 30 bar hydrogen in water in a batch reactor. The desired catalyst should have relatively high metal dispersion and some acidity to facilitate both hydrogenation and hydrogenolysis. However, overhydrogenation and overhydrogenolysis forming 2,5-dimeth-yltetrahydrofuran and methylfuran, respectively, should be suppressed. Furthermore, a hydrophobic support is more selective than oxide-based support. After a careful adjustment of the residence time in a continuous reactor it is also possible to produce high yields of 2,5-dimethylfuran even over Pt/C. The main challenges limiting the industrial feasibility of these reactions are relatively low initial reactant concentration, catalyst deactivation by sintering, leaching and coking. In addition to selection of optimum reaction conditions and catalyst properties, kinetic modelling was also summarized.

“…Also, the Al 2 O 3 adhesion layer was used to reduce the minimum TiO 2 thickness to 5.8 nm. The TiO 2 layer prepared by ALD was able to improve the activity and stability of cobalt/carbon catalysts for electrochemical water oxidation [51] and TiO 2 overcoating could increase Pt-catalyzed acrolein hydrogenation selectivity [52].…”
