“…Fe 3 O 4 @SiO 2 -SO 3 H, was tested for one-pot production of HMF from glucose. 340 A 70.5% yield of HMF with 98% glucose conversion was obtained at optimised reaction conditions. A noticeable decrease in HMF yields from 70.5% to 60.4% was noticed after five recycles of the catalyst, due to accumulation of oligomeric products on the active sites and leaching of acidic species (entry 3, Table 4).…”

Efficient transformation of biomass to value-added chemicals and high-energy density fuels is pivotal for a more sustainable economy and carbon-neutral society. In this framework, developing potential cascade chemical processes using functionalised heterogeneous catalysts is essential because of their versatile roles towards viable biomass valorisation. Advances in materials science and catalysis have provided several innovative strategies for the design of new appealing catalytic materials with well-defined structures and special characteristics. Promising catalytic materials that have paved the way for exciting scientific breakthroughs in biomass upgrading are carbon materials, metal-organic frameworks, solid phase ionic liquids, and magnetic iron oxides. These fascinating catalysts offer unique possibilities to accommodate adequate amounts of acid-base and redox functional species, hence enabling various biomass conversion reactions in a one-pot way. This review therefore aims to provide a comprehensive account of the most significant advances in the development of functionalised heterogeneous catalysts for efficient biomass upgrading. In addition, this review highlights important progress ensued in tailoring the immobilisation of desirable functional groups on particular sites of the above-listed materials, while critically discussing the role of consequent properties on cascade reactions as well as on other vital processes within the bio-refinery. Current challenges and future opportunities towards a rational design of novel functionalised heterogeneous catalysts for sustainable biomass valorisation are also emphasized.

“…Among these, homogenous catalysts like mineral acids, acidic‐ionic liquids etc exhibit several drawbacks with respect to the low selectivity, corrosion of equipment, use of large amounts of catalyst, difficult recovery of catalyst etc . Alternatively, heterogeneous catalysts such as solid acids are becoming more and more attractive due to their stronger acidity and easier regeneration as well as less corrosivity, which accelerate their wide application in production of 5‐HMF from fructose ,,. Currently, various types of solid acid catalysts have been designed for the preparation of 5‐HMF, such as heteropoly acids, tungstated zirconias, cerium phosphates, zirconium phosphates, niobium phosphates, zirconium hydrogen phosphates, carbon catalysts etc.…”

An environmentally benign carbonaceous solid acid was synthesized from microalgae residue discarded after biodiesel production. Thereafter, the as‐synthesized carbonaceous solid acid was used for catalytic dehydration of fructose into 5‐hydroxymethylfurural (5‐HMF). Various techniques such as X‐ray diffraction, N2 adsorption‐desorption, scanning electron microscopy, Fourier transform infrared, Raman, X‐ray photoelectron spectroscopy and pyridine adsorption etc were conducted to elucidate the structural and acidic properties of the solid acid so as to build the structure‐performance relationship. The results suggested that large amounts of ‐SO3H, phenolic ‐OH and ‐COOH groups were grafted onto the investigated material and most of the surface acid sites were assigned to strong Brönsted acid sites. In screening tests with other commercial catalysts, the as‐prepared sample presented excellent catalytic activity with 76.65±2.53% yield of 5‐HMF under aqueous conditions. The dehydration of fructose in dimethyl sulfoxide‐water biphasic system was also tested, affording the 5‐HMF yield as high as 93.84±1.12%. This work provides an efficient and selective solid acid from biodiesel waste and might shed light on an alternative catalyst for highly efficient production of 5‐HMF instead of homogeneous catalysts.

Unlocking the Anion Effect on Steerable Production of 5‐Hydroxymethylfurfural

Homogeneous metal salt catalysts play a pivotal role in industrial production of 5‐hydroxymethylfurfural (HMF). Herein, we first proposed the anion effect on steerable production of HMF using metal salts with different anions as catalyst in a biphasic system of tetrahydrofuran (THF)/NaCl aqueous solution (NaCl aq). Notably, the anions affected the catalytic activity of the metal salts, leading to an order of magnitude difference in the HMF yields, i.e., AlBr3 (74.0 mol %)>AlCl3 (60.8 mol %)>Al2(SO4)3 (35.2 mol %)>Al(NO3)3 (14.9 mol %). The anion effect on steerable production of HMF could be attributed to the proximity effect and electron tension. Anions form close‐range interactions with glucose molecules by proximity effect to promote electron transfer, facilitating the isomerization of glucose to fructose. Besides, anions induce a reduction of the electron cloud density of glucose carbon atoms, generating electron tension that rapidly transforms glucose from the ground state to the transition state, thereby increasing the HMF yield. Based on the revelation of anions effect and evaluation of techno‐economic process, we expect to provides theoretical guidance for high‐throughput screening of metal salt catalysts in industrial biorefinery.
