“…According to the DFT calculation, addition of Au destabilizes ArO* intermediates and decreases the activation barrier between ArO* and H. These studies give clue on the origin of the Au promotional effect but more investigations are still required to reach a decisive conclusion. For instance, mechanism of the C-O bond hydrogenolysis over Re-M (M = Rh, Ir and Ru) is well studied [108,109], and some protocols in these previous reports should be employed to further understand the bimetallic Ni catalyst in lignin C-O bond breakage.…”

This review briefs the emerging strategies for the designing of catalysts and catalytic systems to upgrade waste biomass into value-added chemicals, with an emphasis on the efforts and advances in our group. The review covers the valorization of chitin and lignin materials, which are most abundant N-containing and the most abundant aromatic polymers, respectively. In the chitin part, we show case existing examples on chitin monomer and chitin transformation into renewable, N-containing chemicals. Oxidation, hydrolysis, dehydration reactions will be introduced. In lignin part we mainly introduce novel catalyst for lignin hydrogenolysis, in particular Ni based monometallic and bimetallic catalysts. The structure-activity correlations will be discussed in detail. We finally describe some of the undergoing works in the group and highlight a few potential directions worth investigation in the future.

“…As an alternative, biomass exploitation for chemical production has been intensively targeted to overcome this distress. [3][4][5][6][7][8] Diols, which are among the most appreciated monomers, [9] can be produced viaFA hydrogenation. [1] Among them, furfural (FA) is one of the few which nowadays is completely produced from renewable resources.…”

Insights on the One‐Pot Formation of 1,5‐Pentanediol from Furfural with Co−Al Spinel‐based Nanoparticles as an Alternative to Noble Metal Catalysts

CoAl-spinel nanoparticles prepared by liquid-feed flame spray pyrolysis (LÀ F FSP) and activated by reduction at different temperatures were used to investigate the hydrogenation process of furfural (FA) under mild conditions. Reduction of the spinel at 500°C resulted in high FA conversion and selectivity to furfuryl alcohol (FFA, 81 % yield, in 1 hour). Reduction at higher temperatures (i. e., 700 and 850°C) led to the direct formation of diols (i. e., 1,5-PeD and 1,2-PeD) from FA. The differences in activity are attributed to the formation of surface metallic cobalt nanoparticles upon reduction at high temperature. A maximum of 30 % 1,5-PeD was yielded after 8 hours of reaction under the optimized conditions of150°C, 30 bar of H 2 and with 40 mg of catalyst reduced at 700°C. This is the first report on the direct catalytic conversion of furfural to1,5-pentanediol with a nonnoble metal solid catalyst. either form 1,2-PeD or 1,5-PeD or both. The second one combines hydrogenation of FFA to tetrahydrofurfuryl alcohol (THFA) followed by hydrogenolysis of THFA (Scheme 1, route II). Independently of which one is employed, FFA or THFA are usually chosen as starting reactant to obtain the diols.Due to the high amount of competitive reactions that FA can undergo (Scheme 1), the direct use of FA as starting material remains a challenge. Xu et al. reported 1,5-PeD production from FA over platinum supported inverse Co-spinel,

“…Among them, only biomass can produce both energy and chemicals [1] and, therefore, the research on this field is continuously growing [2]. Some examples of the most relevant biomass-derived platform chemicals studied are furfural and its derivatives, succinic acid, sorbitol, lactic acid or glycerol [3][4][5][6][7]. The latter chemical has received much attention in recent years both from academia and industry due to its high functionalization, high reactivity, availability and low price [8].…”

“…One of the most interesting options is glycerol transformation under hydrogen pressure [2,7,13], consisting in glycerol reduction in such way that there is a dissociation of a C OH chemical bond, the OH group being replaced by a H atom. The main products obtained in glycerol hydrogenolysis are 1-hydroxy-propan-2-one (ACETOL) [14], 1,2-PDO [15], 1,3-PDO [16] and ethylene glycol (EG), the latter involving a C-C cleavage [17].…”
