“…Lignocellulosic biomasses are abundant and inedible resources that can be easily obtainable also from agricultural residues and waste. A variety of chemical routes and industrial processes have been explored to valorize lignocellulosic biomasses [13][14][15][16][17][18][19][20][21][22][23]. Since lignocellulose has a complex "chemical-architecture" [24], one strategy is the first deconstruction into cellulose, hemicellulose and lignin (Figure 1).…”

Abstract:This review provides an overview of heterogeneous bimetallic Pd-Fe catalysts in the C-C and C-O cleavage of platform molecules such as C2-C6 polyols, furfural, phenol derivatives and aromatic ethers that are all easily obtainable from renewable cellulose, hemicellulose and lignin (the major components of lignocellulosic biomasses). The interaction between palladium and iron affords bimetallic Pd-Fe sites (ensemble or alloy) that were found to be very active in several sustainable reactions including hydrogenolysis, catalytic transfer hydrogenolysis (CTH) and aqueous phase reforming (APR) that will be highlighted. This contribution concentrates also on the different synthetic strategies (incipient wetness impregnation, deposition-precipitaion, co-precipitaion) adopted for the preparation of heterogeneous Pd-Fe systems as well as on the main characterization techniques used (XRD, TEM, H 2 -TPR, XPS and EXAFS) in order to elucidate the key factors that influence the unique catalytic performances observed.

“…The development of solid acid catalyst based on metal oxides receives attention in as much as other solid materials such as ion-exchange resin, heteropolyacids, zeolite, carbon mesopore and modified clay [1][2][3][4][5][6][7][8]. Taking economically aspect and ease of synthesis as consideration, metal oxides might the best option to obtain heterogeneous catalyst with strong acidity and good thermal resistance.…”

Sulfated zirconia mesopore has been successfully prepared from zirconyl oxychloride using structure directing agent cetyl trimethyl ammonium bromide (CTAB) and (NH 4 ) 2 SO 4 . The preparation involved calcination at four different temperatures denoted as MZS (400, 500, 600, and 700°C) and three different zirconyl-to-CTAB ratios (1:1, 3:1, and 9:1). Characterization of resulting zirconia was carried out using XRD method, TEM, gas sorption analyzer, and FTIR. The acidity of zirconia evaluated by ammonia adsorption. Calcination temperatures conducted at 500, 600, and 700°C lead to crystalline structure and tetragonal phase. MZS-600 prepared at ratio 3:1 showed optimum specific surface area, pore diameter, and pore volume: 147.5 m 2 /g, 6.6 nm, and 0.396 cc/g, respectively. CTAB assisted larger pore size formation in zirconia along with higher surface area. The catalytic activity of sulfated zirconia mesopore was tested on lauric acid esterification. All sulfated zirconia mesopores prepared were able to give 99-100% conversion. The highest yield of methyl lauric 89.8% was achieved by MZS-600 prepared using CTAB to zirconyl ratio 9:1.

“…Jin and co-workers described the depolymerization of the Kraft lignin using a 2-propanol/water mixture system as solvent/hydrogen source over Fe on Rh/La 2 O 3 /CeO 2 -ZrO 2 catalyst at 373 • C for 2 h. The main products obtained were C 12-26 aliphatic, C [6][7][8][9][10][11][12][13][14][15][16] aromatic, and C 7-10 hydrogenated cycles compounds [145].…”

“…While many criticisms have been raised towards the first generation of bio-energies and biofuels since they are in direct competition with human and animal food, reducing the land availability [7], we have recently achieved significant progress in the production of chemical building blocks and intermediates from lignocellulosic wastes and residues [8][9][10][11][12][13][14][15][16][17][18][19][20]. This is because their use in the chemical industry presents several advantages including: (i) the production of less toxic by-products and lower environmental risks, (ii) the reduction of CO 2 emissions, (iii) a minor dependence on fossil resources and/or foreign commodities, and (iv) the use of indigenous raw materials that can add value in many agriculture products or processes.…”

Catalytic Transfer Hydrogenolysis as an Effective Tool for the Reductive Upgrading of Cellulose, Hemicellulose, Lignin, and Their Derived Molecules

Lignocellulosic biomasses have a tremendous potential to cover the future demand of bio-based chemicals and materials, breaking down our historical dependence on petroleum resources. The development of green chemical technologies, together with the appropriate eco-politics, can make a decisive contribution to a cheap and effective conversion of lignocellulosic feedstocks into sustainable and renewable chemical building blocks. In this regard, the use of an indirect H-source for reducing the oxygen content in lignocellulosic biomasses and in their derived platform molecules is receiving increasing attention. In this contribution we highlight recent advances in the transfer hydrogenolysis of cellulose, hemicellulose, lignin, and of their derived model molecules promoted by heterogeneous catalysts for the sustainable production of biofuels and biochemicals.
