“…Chen et al first fabricated Cu-Al 2 O 3 via co-precipitation using NH 4 OH as the precipitant followed by calcination at 923 K, and then 0.2 wt% Au was supported by the PVP-stabilized colloidal method to give the Au/Cu-Al 2 O 3 catalyst. 61 Au NPs (average size was 3 nm) were evenly dispersed on the surface of Cu-Al 2 O 3 , giving 100% FFA yield using isopropanol as the hydrogen donor at 393 K and 0.1 MPa H 2 for 4 hours with an activation energy of 48 kJ mol −1 and good stability for five recycles. The excellent catalytic performance of Au/Cu-Al 2 O 3 was attributed to the cooperation of the Au NPs and Cu-Al 2 O 3 support.…”

“…In order to solve this issue, developing an exclusive catalytic strategy is highly essential. Compared with the conventional catalytic strategy, − photocatalytic strategy, − electrocatalytic strategy, − photoelectrocatalytic strategy, and disproportionation strategy, − the catalytic transfer hydrogenation (CTH) is a very promising and fascinating strategy because it has a very high selectivity to CO bond hydrogenation, − in which alcohols (especially secondary alcohols) are commonly employed as in situ hydrogen donors as well as green reaction solvents. In this respect, it is particularly noteworthy that zirconium-containing coordination catalysts with acid–base bifunctional properties have extensively been proven to be efficient for the selective synthesis of BHMF from HMF via CTH.…”

Constructing a cheap and high-performance catalyst is very important for the selective synthesis of biomass-based 2,5-bis(hydroxymethyl)furan (BHMF) from 5-hydroxymethylfurfural via the strategy of catalytic transfer hydrogenation (CTH). Herein, we synthesized a neoteric zirconium–carbon coordination catalyst (Zr-HTC) via a simple self-assembly method, in which glucose-derived hydrothermal carbon (HTC) containing abundant carboxyl and phenolic hydroxyl groups was directly used as a low-cost organic ligand. Satisfyingly, Zr-HTC showed an outstanding catalytic activity for the selective synthesis of BHMF in isopropanol (iPrOH). After 4 h at a mild temperature of 120 °C, 99.2% BHMF yield with 5.61 h–1 turnover frequency (TOF) could be obtained. Detailed experimental results demonstrated that this outstanding catalytic activity of Zr-HTC was mainly contributed by the synergetic effects of Lewis acid–base sites (Zr4+–O2–) with high contents, proper ratios, and strengths under the aid of good hydrophilicity. In addition, Zr-HTC displayed superior catalytic stability, and when it was repeatedly used for five reaction cycles, no noticeable decrease in BHMF yield was found. More significantly, Zr-HTC could also effectively convert a wide range of carbonyl compounds, such as 1-butanal, 1-hexanal, furfural, cyclohexanal, benzaldehyde, phenylacetaldehyde, cyclopentanone, cyclohexanone, levulinic acid, and ethyl levulinate, to the relevant products in iPrOH. Overall, this work offers a new viewpoint to develop more practical zirconium-containing coordination catalysts for the selective synthesis of valuable chemicals via CTH.

“…2-Propanol and tert-butanol are used as solvents in hydrogenation reactions primarily as an additional source of hydrogen during hydrogen transfer hydrogenation. 53 The BHMF yield in water was extremely low and reached only 28% (Figure 5a). The product yield with the use of 2propanol and tert-butanol as solvents was 60 and 26%, respectively.…”

The use of available renewable sources of raw materials for the production of various organic compounds has long been undoubted and recognized throughout the world. However, the development of efficient “green” catalytic technologies for the processing of bioavailable compounds, namely, the synthesis of catalysts and the selection of optimal process conditions, has become a real challenge for researchers nowadays. In this work, 2,5-bis(hydroxymethyl)furan, an intermediate for the production of a number of biobased polymer materials, was obtained by hydrogenation of 5-hydroxymethylfurfural in a yield close to quantitative at room temperature and atmospheric pressure in the presence of a catalytic system with 1% wt of platinum as an active phase supported on ceria–zirconia mixed oxide. On the low-loaded 0.25% Pt/CeO2–ZrO2 catalyst, the yield of the desired alcohol as high as 87% has been achieved after a slight increase of H2 pressure from 0.1 to 0.5 MPa.
