“…The depletion of fossil resources has attracted considerable interest in the valorization of renewable biomass materials for the production of valuable chemicals. The catalytic conversion of naturally occurring sugars, such as xylose and glucose, into their corresponding sugar alcohols is an attractive pathway for the production of value added chemicals, such as sweeteners and pharmaceutical intermediates [1][2][3][4][5][6][7][8][9][10][11]. Xylitol is an important artificial sweetener and has been widely used in various fields [12][13][14][15][16].…”

A disadvantage of the commercial Raney Ni is that the Ni active sites are prone to leaching and deactivation in the hydrogenation of xylose to xylitol. To explore a more stable and robust catalyst, activated carbon (AC) supported Ni-Re bimetallic catalysts (Ni-Re/AC) were synthesized and used to hydrogenate xylose and hemicellulosic hydrolysate into xylitol under mild reaction conditions. In contrast to the monometallic Ni/AC catalyst, bimetallic Ni-Re/AC exhibited better catalytic performances in the hydrogenation of xylose to xylitol. A high xylitol yield up to 98% was achieved over Ni-Re/AC (n Ni :n Re = 1:1) at 140 • C for 1 h. In addition, these bimetallic catalysts also had superior hydrogenation performance in the conversion of the hydrolysate derived from the hydrolysis reaction of the hemicellulose of Camellia oleifera shell. The characterization results showed that the addition of Re led to the formation of Ni-Re alloy and improved the dispersion of Ni active sites. The recycled experimental results revealed that the monometallic Ni and the bimetallic Ni-Re catalysts tended to deactivate, but the introduction of Re was able to remarkably improve the catalyst's stability and reduce the Ni leaching during the hydrogenation reaction.

“…[30] Usually, the oxidation of HMF is performed using homogeneous, heterogeneous or electrocatalytic routes. [31] In addition to these routes, photocatalysis has received considerable prominence since a natural, free and abundant energy source can be exploited, that is, solar energy. As a consequence, several catalysts have been developed with the aim of maximizing the efficiency of light absorption in the conversion of HMF, as well as attaining the selectivity for the desired products.…”

The use of graphitic carbon nitride (g‐C3N4)‐based catalysts in the upgrading of lignocellulosic biomass significantly contributes to the greener production of biofuels, polymer precursors, and building blocks. In recent years, several catalysts based on g‐C3N4 have been developed and applied in both photocatalyzed and non‐photocatalyzed (thermal) reactions. This Review provides an overview on the upgrading of lignocellulosic biomass deploying several compositions of g‐C3N4‐based catalysts.

“…Monomer and polymer production from renewable feedstocks has become a relevant research target with the aim of providing more environmental friendly solutions to the actual fossil-based market [1][2][3][4][5][6]. In this framework, 5-(hydroxymethyl)furfural (HMF) is recognized as an ideal platform molecule to develop different green products, since it can be obtained via acid-catalyzed dehydration of biomass-derived sugars [7][8][9], and, in turn, it can be converted into a wide range of different high added value chemicals [10][11][12][13]. Among the HMF products, 2,5-furandicarboxylic acid (FDCA, Scheme 1) has been identified as one of the most interesting [14], since it can be considered as the bioderived counterpart of terephthalic acid for the production of polyesters [15], such as polyethylene 2,5-furandicarboxylate First attempts to industrially convert HMF to FDCA relied on the technologies developed for terephthalic acid production [18].…”

Pd/Au Based Catalyst Immobilization in Polymeric Nanofibrous Membranes via Electrospinning for the Selective Oxidation of 5-Hydroxymethylfurfural

Innovative nanofibrous membranes based on Pd/Au catalysts immobilized via electrospinning onto different polymers were engineered and tested in the selective oxidation of 5-(hydroxymethyl)furfural in an aqueous phase. The type of polymer and the method used to insert the active phases in the membrane were demonstrated to have a significant effect on catalytic performance. The hydrophilicity and the glass transition temperature of the polymeric component are key factors for producing active and selective materials. Nylon-based membranes loaded with unsupported metal nanoparticles were demonstrated to be more efficient than polyacrylonitrile-based membranes, displaying good stability and leading to high yield in 2,5-furandicarboxylic acid. These results underline the promising potential of large-scale applications of electrospinning for the preparation of catalytic nanofibrous membranes to be used in processes for the conversion of renewable molecules.
