“…Functionalized M-BCH catalysts can be applied for a broad variety of reactions involved in biorefineries processes to substitute the traditional petrochemical industry. In this section, the use of biochars as versatile catalyst supports for biomass upgrading is evaluated sorting them into transesterification, reforming/gasification, pyrolysis, Fischer-Tropsch synthesis, hydrolysis, hydrogenation/hydrodeoxygenation, and isomerization reactions [3,29,32].…”

“…Biochar can be also applied as the catalyst support for the hydrotreating process (Table 2). There is a recent review on this topic by Wang et al [3]. with fresh advances in the preparation of M-BCH catalysts and catalytic performance for hydrogenation of biomass.…”

“…Performing the reactions with phenolic and furan derivatives model compounds, it is possible to find that noble metal-supported biochar catalysts exhibits better performance in hydrogenation and non-noble metal-supported biochar catalysts favors deoxygenation which is a result of their effective oxygen affinity ability. A synergistic effect of the combination of bimetals can strongly improve hydrogenation/deoxygenation, so further studies of catalyst optimization are necessary to enhance the potential of M-BCH catalysts for biomass upgrading in the biorefinery context [3].…”

“…Above all, thermochemical processes-such as pyrolysis, gasification, and hydrothermal treatments-are characterized by a strong efficiency, in terms of quality and yield, to provide biofuels (e.g., syngas and bio-oil) [2]. Furthermore, during thermochemical processing takes place the production of biochar as a solid carbon-rich residue formed via biomass thermal degradation (pyrolysis: 300-900 • C) [3] in an oxygen-limited environment. In comparison with other carbon materials typically synthesized by complex and energy-consuming processes (e.g., activated carbons, nanotubes/nanofibers and carbon black synthesized via vapor deposition, or polymer carbonization routes), biochar is a greener solid produced by cost-competitive processes that may valorize biomass wastes formed in forthcoming biorefineries, thus reducing their environmental impact [4,5].…”

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.

Adipic acid (AA) is a key industrial dicarboxylic acid intermediate used in nylon manufacturing. Unfortunately, the traditional process technology is accompanied by serious environmental pollution. Given the growing demand for adipic acid and the desire to reduce its negative impact on the environment, considerable efforts have been devoted to developing more green and friendly routes. This Review is focused on the latest advances in the sustainable preparation of AA from biomassbased platform molecules, including 5-hydroxymethylfufural, glucose, γ-valerolactone, and phenolic compounds, through biocatalysis, chemocatalysis, and the combination of both.Additionally, the development of state-of-the-art catalysts for different catalytic systems systematically is discussed and summarized, as well as their reaction mechanisms. Finally, the prospects for all preparation routes are critically evaluated and key technical challenges in the development of green and sustainable processes for the manufacture of AA are highlighted. It is hoped that the green adipic acid synthesis pathways presented can provide insights and guidance for further research into other industrial processes for the production of nylon precursors in the future.
