“…39 Furfural can be converted to 2-methylfuran over supported biobased catalysts. 40 Furthermore, high phenolic concentrations on fractionated lignocellulose streams have been shown to boost antioxidant activity. 41 The pretreatment of lignocellulose samples using GVLbased solvolysis demonstrates an effective pathway to obtain platform chemicals and alternative quality biofuels that can be recovered by a combined cascading approach.…”

Technological development made in the field of biomass application allows synthesizing several high-value products, such as furfuraldehyde. Furfural, produced through sequential hydrolysis and dehydration reactions from biomass, is considered a platform molecule and a precursor of several other chemicals and biofuels that are generated following reactions such as hydrogenation, hydrodeoxygenation, and decarboxylation. This review aims to reveal the environmental-friendly mechanisms followed for producing furfural derivatives and the design of catalysts and supports. Redox and acid-base properties of the molecules have been discussed. The stability, the details of the surface area, and the applications of the molecules to reduce the bottlenecks faced in the industrial production of bioproducts have been explored.

“…Cobalt-based catalysts are excellent catalysts for biomass transfer hydrogenation using isopropanol as hydrogen source and solvent. Most of the reported supported catalysts prepared from cobalt and tannic acid were used for the hydrogenation of the halogenated aromatic or the degradation of dyes ( Wang et al, 2020 ; Choi et al, 2021 ; Varila et al (2021) . To the best of our knowledge, the direct use of tannic acid derived carbon supported transition metal cobalt catalysts for the CTH reaction of EL has not been reported.…”

The catalytic conversion of ethyl levulinate (EL) to γ-valerolactone (GVL) is an important intermediate reaction in the conversion and utilization of biomass resources. The development of novel and efficient catalysts is significantly important for this reaction. In this work, using the biomass-derived tannic acid as carbon precursor and the transition metal cobalt as active component, a novel tannic acid carbon supported cobalt catalyst (Co/TAC) was prepared by pyrolysis and subsequent hydrazine hydrate reduction method. The hydrogenation of EL and other carbonyl compounds by hydrogen transfer reaction was used to evaluate the performance of the catalysts. The effects of different preparation and reaction conditions on the performance of the catalysts were investigated, and the structures of the prepared catalysts were characterized in detail. The results showed that the carbonization temperature of the support had a significant effect on the activity of the catalyst for the reaction. Under the optimized conditions, the Co/TAC-900 catalyst obtained the highest GVL yield of 91.3% under relatively mild reaction conditions. Furthermore, the prepared catalyst also showed high efficiency for the hydrogenation of various ketone compounds with different structures. This work provides a new reference for the construction of the catalysts during the conversion of biomass and a potential pathway for the high-value utilization of tannin resource.
