“…Furthermore, hydrogenation of furfural with Ni catalysts supported on Mg‐Al mixed metal oxide, Mg/Al/Ni, also resulted in 97.6 % conversion to furfuryl alcohol (94.5 % selectivity) with 1 atm H 2 gas at 180 °C . Study inferred that the metallic Ni is the active site for the hydrogenation reaction, whereas surface basic sites near metallic Ni interacted with the π* acceptor orbital of C=O bond and facilitated feasible adsorption of furfural on the catalyst surface.…”

Catalytic transformation of biomass‐derived compounds to different platform chemicals and liquid fuel is a prominent way to reduce the global dependence on fossil resources. In past few decades, biomass‐derived furans such as 2‐furfuraldehyde (furfural) and 5‐hydroxymethyl‐2‐furfural (HMF) have received outstanding attention because of their wide applications in the production of various industrially important value‐added chemicals and fuel components. Various catalytic systems and methodologies have been extensively explored for the transformation of these furans to a wide range of products including open ring diketones, ketoacids, alcohols and long chain alkanes. This Review is aimed to provide an extensive overview of the recent developments of several high‐performing heterogeneous catalysts for the catalytic upgradation of the key biomass‐derived furans (furfural and HMF) to value‐added chemicals. Moreover, the role of these catalysts in the catalytic transformations including hydrogenation, decarbonylation, oxidation, hydrogenolysis and ring opening reactions, and the mechanistic pathways are also highlighted in this Review.

“…In a more recent report, Manikandan et al 107 used the same type of hydrotalcite precursor to synthesize Ni-supported catalysts for the selective vapor phase hydrogenation of furfural at ambient pressure. One of the main issues related to the utilization of Ni supported catalysts for this reaction is the strong hydrogenation capacity of this metal, which favors the formation of tetrahydrofurfuryl alcohol instead of furfuryl alcohol.…”

“…108 Nonetheless, it was established that the surface synergistic interactions between the active metallic Ni sites and the strong basic sites from the hydrotalcite-derived support highly favored the selectivity of the reaction, achieving 95% selectivity towards the production of furfuryl alcohol, at 98% conversion (gas phase hydrogenation). 107 These authors remarked that the strong surface basic sites in close proximity with Ni 0 sites can interact with the π* acceptor orbital of the CvO group to enhance the reactivity of the carbonyl group. The uniform distribution of the Ni and Mg(Al)O species in the catalyst precursor was optimized by fine-tuning the Mg-to-Ni ratio used for the preparation of the LDH structure, which allowed an improved synergistic interaction between the involved active places.…”

Recent advances on the utilization of layered double hydroxides (LDHs) and related heterogeneous catalysts in a lignocellulosic-feedstock biorefinery scheme

Layered double hydroxides (LDHs) and derived materials have been widely used as heterogeneous catalysts for different types of reactions either in gas or in liquid phase. Among these processes, the valorization/upgrading of lignocellulosic biomass and derived molecules have attracted enormous attention because it constitutes a pivotal axis in the transition from an economic model based on fossil resources to one based on renewable biomass resources with preference for biomass waste streams. Proof of this is the increasing amount of literature reports regarding the rational design and implementation of LDHs and related materials in catalytic processes such as: depolymerization, hydrogenation, selective oxidations, and C-C coupling reactions, among others, where biomass-derived compounds are used. The major aim of this contribution is to situate the most recent advances on the implementation of these types of catalysts into a lignocellulosic-feedstock biorefinery scheme, highlighting the versatility of LDHs and derived materials as multifunctional, tunable, cheap and easy to produce heterogeneous catalysts.

Aqueous-phase processing of biomass-derived furfural is one of the promising ways to convert biomass into useful chemicals. Supported metal catalysts are crucial in the aqueous-phase hydrogenation of furfural. Understanding the effect of acid and basic properties of supports on the performance of the catalysts will help understand the reaction pathways and develop more efficient catalysts. Here, a series of Cu-based catalysts with different supports (Al 2 O 3 , ZnO, SiO 2 , MgO, and ZSM-5) have been investigated in hydrogenation of furfural in aqueous phase. The properties of the supports have been characterized by X-ray diffraction, N 2 adsorption-desorption, transmission electron microscope, H 2 temperatureprogrammed reduction, and CO 2 and NH 3 temperature-programmed desorption. The results show that pure acid support leads to the formation of oligomers and pure basic support results in furfuryl alcohol as the main product. And the mass balance in reaction system catalyzed by Cu-based catalysts with higher acidity amount is lower.
