“…[1] The global market for transforming biomass and waste into energy, valued at $ 30.5 billion in 2022, is projected to grow at a compound annual growth rate (CAGR) of 5.2 %, reaching a size of $ 38 billion by 2026, which indicates the strong determination of governments to accelerate the development of renewable energies. [2] Lignocellulosic biomass is composed of three major components: cellulose (30-50 wt.%), hemicellulose (20)(21)(22)(23)(24)(25)(26)(27)(28)(29)(30)(31)(32)(33)(34)(35) wt.%), and lignin (15-20 wt.%); [3] therefore, the conversion of cellulose into biofuels and fine chemicals is of utmost importance for the efficient utilization of lignocellulosic biomass. [4][5] Cellulose is a polymer of glucose linked by a linear β-1,4-glycosidic bond and is the most abundant polysaccharide on Earth.…”

“…Reaction rates, product yields, and selectivity (generally detected by High-performance liquid chromatography (HPLC) and Gas chromatography (GC)) are closely tied to these factors. A range of homogeneous catalysts (such as inorganic acids, [19] metal chlorides, [20] and acid-functionalized ionic liquids [21] ) and heterogeneous catalysts (including zeolites, [22] metal oxides, [23] carbon-based catalysts, [24] and functionalized silica materials [25] ) have been employed in cellulose-to-HMF reactions across various solvents (aqueous, organic, ionic liquid, and biphasic). Both types of catalyst systems have their own advantages and disadvantages.…”

The catalytic conversion of lignocellulose‐derived carbohydrates, particularly cellulose, into 5‐hydroxymethylfurfural (HMF), holds significant potential as a crucial step in the sustainable production of valuable platform chemicals. This review presents the remarkable progress made in the field, with a specific emphasis on the role of heterogeneous catalysts, innovative methods for accelerating cellulose hydrolysis, and the design of flow reactor technologies. The distinctive properties and surface functionalities of catalysts facilitate the efficient breakdown of cellulose's intricate structure, thereby promoting selective hydrolysis leading to HMF formation. Therefore, this review comprehensively examines various categories of heterogeneous catalysts, including metal oxides/phosphates, zeolites, functionalized silica/carbon‐based materials, heteropolyacids (HPAs), and metal‐organic frameworks (MOFs), highlighting their unique mechanisms and performance in cellulose conversion. Furthermore, the review describes the intriguing progress in hydrolysis strategies (pretreatment techniques and advanced heating systems) that have been crucially involved in overcoming the challenges associated with cellulose recalcitrance and achieving enhanced HMF yields. The synergistic interactions between catalysts and innovative hydrolysis methods have played a central role in the breakthroughs within cellulose conversion technology. Another aspect covered in this work is the advancement in using fixed‐/fluidized‐bed reactors and slug microreactors for the continuous production of HMF. Lastly, the current challenges and future perspectives are presented to propose the dilemma and development direction for efficient cellulose‐to‐HMF conversion.

Catalysts are very important in the use of cellulose, the main component of biomass, as a raw material for the large-scale production of liquid fuels and chemicals. 5-Hydroxymethylfurfural (HMF) is an extremely important intermediate in the fine chemical industry. HMF can be synthesized by acid-catalyzed dehydration of fructose, glucose, cellulose, or sucrose. The conversion of cellulose to HMF is challenging due to its chemical structure. The objective of the present study was to devise a more facile synthesis method using transition metal-doped montmorillonite catalysts (10Cr-Mnt, 10Cu-Mnt, 10Fe-Mnt, and 10Zn-Mnt) by wet impregnation. Samples were characterized by X-ray powder diffraction, specific surface area, and NH3-TPD analyses. The synthesized catalysts were used for the conversion of cellulose to 5-HMF in an aqueous medium. Among the metals studied, Cr showed the greatest catalytic activity. With the use of this catalyst, efficient conversion of cellulose to 5-HMF was achieved, affording a conversion yield of 93.47% and 5-HMF yield of 9.07% within 6 h at 200°C. The study described here could be useful for the efficient conversion of cellulose into 5-HMF, as well as into other biomass-derived chemicals.
