“…To date, there are several review articles on the catalytic hydrogenation of LA to GVL. All these reviews focus on either noble metal [33,[47][48][49] or non-noble metals [50] as catalysts. Of all these review articles, only one recently published review by Seretis et al [48] has focused on the heterogeneous and homogeneous Ru-based catalysts for this hydrogenation of LA to GVL.…”

Catalytic hydrogenation of a biomass-derived molecule, levulinic acid (LA), to γ-valerolactone (GVL) has been getting much attention from researchers across the globe recently. This is because GVL has been identified as one of the potential molecules for replacing fossil fuels. For instance, GVL can be catalytically converted into liquid alkenes in the molecular weight range close to that found in transportation fuels via a process that does not require an external hydrogen source. Noble and non-noble metals have been used as catalysts for the selective hydrogenation of LA to GVL. Of these, Ru has been reported to be the most active metal for this reaction. The type of metal supports and solvents has been proved to affect the activity, selectivity, and yields of GVL. Water has been identified as a potential, effective “green” solvent for the hydrogenation of LA to GVL. The use of different sources of H2 other than molecular hydrogen (such as formic acid) has also been explored. In a few instances, the product, GVL, is hydrogenated further to other useful products such as 1,4-pentanediol (PD) and methyl tetrahydrofuran (MTHF). This review selectively focuses on the potential of immobilized Ru catalysts as a potential superior catalyst for selective hydrogenation of LA to GVL.

“…The heterogeneous catalysts are preferred in biorefinery processes compared to their homogeneous counterpart mostly due to their straightforward recovery . Solid acids (e.g., zeolite, acidic resins) are preferred over mineral acids for acid-catalyzed transformations, whereas metal-based supported heterogeneous catalysts have been developed for redox reactions. , The development of multifunctional catalysts capable of promoting more than one type of reaction in a single pot is actively pursued . The recently developed nanocatalysts and single-atom catalysts have shown unprecedented activity and are bridging the gap between homogeneous and heterogeneous catalysts and are increasingly being used in sustainable synthesis. − Organocatalysts have also received significant interests over the last two decades due to their high efficiency and eco-friendly nature .…”

Reagentless organic synthesis (ROS) can be envisaged as a corollary of the principles of green chemistry, wherein the reactant molecules undergo chemical transformations under the influence of heat, light, sound, or electricity and afford the desired product without necessitating stoichiometric reagents. The predominantly catalytic processes ensure excellent atom economy and minimize waste formation, making the synthetic strategies inherently green. However, since most starting materials stem from exhaustible resources like petroleum, the processes are not entirely sustainable. Reagents and reactants are often used interchangeably, but utmost care should be taken to minimize or eliminate the use of any chemical or material in a chemical transformation that does not appear in a balanced chemical equation. The ideal disposition would be the reagentless synthesis of chemicals using renewable starting materials. In this regard, biomass is a renewable carbon source with the commercial potential to supplant petroleum in producing fuels, chemicals, and polymers. Even though many chemocatalytic biomass value addition processes can be contemplated as ROS, they are somewhat scattered in the literature and have never been deliberated coherently from this perspective. Integration of ROS with biorenewable starting materials can ensure the much-anticipated all-round sustainability of the organic chemical industry. This unique review discusses the merits of synthesizing fuels and chemicals from biomass components following reagentless synthetic steps, critically analyzes the literature data, identifies the research gaps, and proposes future directives.

“…158 In the case of RuCo/CoOx catalyst, two important synergistic effects, namely, (i) RuCo nanoparticles and the high density of defective sites on the surface and (ii) the unique dandelion-like nanostructuring of RuCo nanoparticles and the spillover effect of hydrogen, collectively improve the DMF production rate. 159 CuRu/C could also provide 71% DMF yield after 10 h of batch reaction in the presence of 1-butanol under optimum conditions (220 °C, 6.8 bar of H 2 pressure). 160 In general, molecular H 2 was considered as the H 2 source in reactions of HMF HDO, although the employment of hydrogen-transfer reagents was thought to be relatively safer.…”

The development of renewable energy resources is strongly urged to recoup the shortage of fossil-based energy and its associated pollution issues. Energy production from carbohydrate materials has recently been of great interest due to the availability, reliability, and abundance of carbohydrate sources. Significantly, the catalytic transformation of waste carbohydrates into furanbased biofuels, specifically 2,5-dimethylfuran (DMF), appears to be an attractive solution to the aforementioned energy and environmental issues. The potential of DMF as a renewable fuel is prospective, with its physicochemical properties that are similar to those of fossil fuels. Therefore, the current work focuses on the production of DMF, with the important aspects for enhanced DMF yield being summarized herein. Notably, the significant catalysts derived from zeolite, noble-metal, non-noble-metal, metal− organic framework, and electrocatalytic materials are discussed, alongside their effects in deriving carbohydrates to DMF. Furthermore, the mechanisms of DMF production were clarified too, followed by the scrutinization of the effects from reaction conditions, solvents, and hydrogen donors onto the DMF yield. Finally, the purification process, commercialization potential, and economic feasibility of DMF production were incorporated too, with insightful future directions being identified at the end of our review. This review is expected to advocate DMF production from carbohydrate materials, which could alleviate the energy and environmental problems encountered presently.
