“…From a mechanistic point of view, these results could be possibly explained, since the most stable adsorption conformation of furfural was with the furan ring lying flat on the Pt (111) surface [162], favoring its hydrogenation. Indeed, catalytic systems that are based on Pd nanoparticles supported on different materials, such as carbon, bio-char, TiO 2 , and Al 2 O 3 , among others, would result in different yields of FA and THFA [87,91,[163][164][165][166]. Some of them exhibited excellent catalytic performance, for example, Pd supported on hydroxyapatite (HAP) and MIL-101(Cr)-NH 2 gave rise to 100% THFA yield [88,89].…”

Furfural has been considered as one of the most promising platform molecules directly derived from biomass. The hydrogenation of furfural is one of the most versatile reactions to upgrade furanic components to biofuels. For instance, it can lead to plenty of downstream products, such as (tetrahydro)furfuryl alcohol, 2-methyl(tetrahydro)furan, lactones, levulinates, cyclopentanone(l), or diols, etc. The aim of this review is to discuss recent advances in the catalytic hydrogenation of furfural towards (tetrahydro)furfuryl alcohol and 2-methyl(tetrahydro)furan in terms of different non-noble metal and noble metal catalytic systems. Reaction mechanisms that are related to the different catalytic materials and reaction conditions are properly discussed. Selective hydrogenation of furfural could be modified not only by varying the types of catalyst (nature of metal, support, and preparation method) and reaction conditions, but also by altering the reaction regime, namely from batch to continuous flow. In any case, furfural catalytic hydrogenation is an open research line, which represents an attractive option for biomass valorization towards valuable chemicals and fuels.FA is a very important monomer for the synthesis of furan resins, which are widely used in thermoset polymer matrix composites, cements, adhesives, coatings, and casting/foundry resins. This molecule is also used as a non-reactive diluent for epoxy resin, a modifier for phenolic and urea resins, an oil well, and a carbon binder. Furthermore, the salt of FA is used in the synthesis of lysine, vitamin C, lubricants, and plasticizers [22,23]. Moreover, it should be highlighted that FA is also an important intermediate for the production of further hydrogenation products (as shown in Scheme 1), such as 2-methylfuran (MF), a potential alternative fuel with better combustion performance and higher Research Octane Number (RON = 103) than that of gasoline (RON = 96.8) [24]. In other applications, MF is used in perfume intermediates, chloroquine lateral chains in medical intermediates, and as a raw material for the production of chrysanthemate pesticides [25].Moreover, tetrahydrofurfuryl alcohol (THFA) can be used as a green solvent in the pharmaceutical industry and, in addition, it constitutes an outstanding intermediate to produce dihydropyran [26], pyridine [27], tetrahydrofuran, and pentan-1,5-diol [28][29][30]. Particularly, the latest molecule is an important monomer in the plastics industry. Furthermore, 2-methyltetrahydrofuran (MTHF) is quite engaging for its possible applications in organometallic chemistry, as well as in organic reactions that are related to organocatalysis, biotransformations, and biomass processing [31].

“…Based on the analysis of the products, the authors proposed that using the Ni-Mo 2 C/BCH the potential mechanism for the reaction is the catalytic depolymerization of lignin. Another example of hydrogenation reaction over a M-BCH catalyst was carried out by Casoni et al using sunflower seed hulls as raw material to produce furfuryl alcohol [48]. The method involved initial fast pyrolysis of the pre-treated hulls to produce bio-oil rich in furfural and biochar as a side product, followed by the catalytic hydrogenation of such furfural over Pd-supported biochar.…”

Metal-Supported Biochar Catalysts for Sustainable Biorefinery, Electrocatalysis, and Energy Storage Applications: A Review

et al. 2022

Biochar (BCH) is a carbon-based bio-material produced from thermochemical conversion of biomass. Several activation or functionalization methods are usually used to improve physicochemical and functional properties of BCHs. In the context of green and sustainable future development, activated and functionalized biochars with abundant surface functional groups and large surface area can act as effective catalysts or catalyst supports for chemical transformation of a range of bioproducts in biorefineries. Above the well-known BCH applications, their use as adsorbents to remove pollutants are the mostly discussed, although their potential as catalysts or catalyst supports for advanced (electro)catalytic processes has not been comprehensively explored. In this review, the production/activation/functionalization of metal-supported biochar (M-BCH) are scrutinized, giving special emphasis to the metal-functionalized biochar-based (electro)catalysts as promising catalysts for bioenergy and bioproducts production. Their performance in the fields of biorefinery processes, and energy storage and conversion as electrode materials for oxygen and hydrogen evolutions, oxygen reduction, and supercapacitors, are also reviewed and discussed.

Herein, an eco-friendly palladium-catalyzed tandem reaction for the one-pot synthesis of carbazoles under microwave irradiation is reported. This approach involves an amination and a direct arylation from available and inexpensive anilines and 1,2-dihaloarenes. For the development of this purpose, a novel recoverable palladium nanocatalyst supported on a green biochar under ligand-free conditions is used. Compared to other existing palladium-based protocols, the present synthetic methodology shows a drastic reduction in reaction times and excellent compatibility with different functional groups allowing to obtain a small library of carbazoles with high yields and regioselectivity. The novel heterogeneous palladium nanocatalyst can be recycled and reused up to 5 times without significant loss activity
