“…[216] 1,2-PD was produced with 53 % selectivity (51 % conversion): the presence of Mo oxides promoted the selective adsorption of the secondary -OH of GL and the phosphotungstic acid helped the initial dehydration. [216] The same group prepared Ru-Mo supported on active carbon modified by phosphotungstic acid: at 40 bar and 473 K, the main products were 1,2-PD (74 % selectivity) and 1,3-PD (21 %). [217] The addition of copper to Ru nanoparticles, dispersed on multiwall carbon nanotubes by wet impregnation, significantly affected the reducibility of the metallic species, promoting the CÀ O cleavage.…”

Glycerol (GL) represents a widespread agro‐industrial waste. Its valorization is pivotal for a sustainable society because GL is a renewable compound deriving from biomass, but it has a high oxygen to carbon ratio, compared with feedstock used in the energy and chemistry sectors. Oxygen‐poor derivatives are easily and immediately transferable to the industry, avoiding a deep and pressing modification of the plants. From this perspective, keeping the carbon content but with an oxygen content reduction, we could effectively obtain the enhancement of the recovery and the use of GL converting it into attractive industrial building‐blocks. In this Review, we present and discuss the up‐to‐date results about the chemical reduction of GL into products with 3 carbon and 0, 1, or 2 oxygen atoms. The focus is on the transition metal (TM) catalysts that have made the hydrogenation reactions of GL possible, partitioning the metals into early and late, based on their position in the periodic table. This discussion will contribute to select and develop new catalysts aimed at the improvement of the yield and of the selectivity in the hydrogenation reactions of GL.

“…Due to the high O/C ratio of glycerol, hydrogenolysis of the C−O bond is an important reaction used to decrease the oxygen content in a substrate [4] . Transformation of glycerol to 1,2‐propanediol, 1,3‐propanediol and propanols is an attractive approach to utilize the surplus glycerol and can be implemented in existing biodiesel processes to improve sustainability [3a,5] . In particular the transformation of glycerol to propanols is of great interest since this alcohol can easily be transformed to propylene and propylene oxide (key commodity chemicals for the polymer industry) using available commercial infrastructures [6] .…”

Selective hydrogenolysis of glycerol to propanol is a sustainable reaction, which can play a critical role in the future of the propylene market, as one step dehydration of this sustainable propanol provides access to sustainable propylene. In this work, Copper (Cu) -Tungstosilicic acid (HSiW) catalysts were studied for the hydrogenolysis of glycerol. For the first time over a Cu catalyst, this study reports a yield of ~76 % for direct conversion of glycerol to propanols in continuous flow mode. Several advanced characterization techniques were employed to study the fresh and used catalysts. The presence of intact Keggin units of HSiW solid acid (with medium acidity) in the vicinity of small clusters of copper sites improved the performance and lifetime of these bifunctional catalysts. This study offers insights into the nature of the active sites required for the hydrogenolysis reaction, which was achieved without using expensive PGMs.

Conversion of biomass-derived furfural platform compound to value-added tetrahydrofurfuryl alcohol (THFL) molecule is a sustainable route, and an efficient nonnoble metallic catalyst is a key factor for this reaction. In this work, Ni@C@CNT composite as a highly effective catalyst for hydrogenation of furfural to tetrahydrofurfuryl alcohol was synthesized by one-step pyrolysis of Nicentered metal organic framework (Ni-MOF) doping with carbon nanotube (CNT). For comparison, Ni@C catalyst derived directly from Ni-MOF was also synthesized. The characterization results show that the doping of CNT promotes high dispersion of active sites and formation of Ni 3 C phase which has Pt-like catalytic activity. Therefore, the obtained Ni@C@CNT exhibited excellent activity in furfural hydrogenation (99.1% furfural conversion and 94.7% THFL yield at 120 C, 4 h, 4-MPa initial hydrogen pressure). Ni@C@CNT also shows good stability in reuse test. Current work presents a facile method for preparation of nonnoble metallic catalysts with high efficiency.
