“…171 The optimisation of hydrothermal carbonisation conditions, such as temperature and time, was undertaken to prepare a glucose-derived carbon, which was then functionalised with -SO 3 H species. 172 The resulting catalyst showed good activity in cellulose hydrolysis and fructose dehydration reactions with glucose and HMF yields of 44 wt% and 20 wt%, respectively. A one-pot synthesis of -SO 3 H and COOH-functionalised carbon solid acids was successfully performed by hydrothermal carbonisation of glucose in the presence of sulfosalicylic acid and acrylic acid, respectively.…”

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.

“…The hydrolysis of lignocellulosic biomass to produce monosaccharides or oligosaccharides is a crucial step for the conversion of biomass to various platform chemicals (e.g., HMF and furfural) and biofuel (e.g., ethanol) [194,195]. Hydrolysis can be catalyzed by Brønsted acids at the temperature range of 90-260 • C [196].…”

Firstly, this paper reviews two main methods for biochar synthesis, namely conventional pyrolysis and hydrothermal carbonization (HTC). The related processes are described, and the influences of biomass nature and reaction conditions, especially temperature, are discussed. Compared to pyrolysis, HTC has advantages for processing high-moisture biomass and producing spherical biochar particles. Secondly, typical features of biochar in comparison with other carbonaceous materials are summarized. They refer to the presence of inorganics, surface functional groups, and local crystalline structures made up of highly conjugated aromatic sheets. Thirdly, various strategies for biochar modification are illustrated. They include activation, surface functionalization, in situ heteroatom doping, and the formation of composites with other materials. An appropriate modification is necessary for biochar used as a catalyst. Fourthly, the applications of biochar-based catalysts in three important processes of biofuel production are reviewed. Sulfonated biochar shows good catalytic performance for biomass hydrolysis and biodiesel production. Biodiesel production can also be catalyzed by biochar-derived or -supported solid-alkali catalysts. Biochar alone and biochar-supported metals are potential catalysts for tar reduction during or after biomass gasification. Lastly, the merits of biochar-based catalysts are summarized. Biochar-based catalysts have great developmental prospects. Future work needs to focus on the study of mechanism and process design.

“…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. Among these various candidates, carbonaceous solid acids have attracted considerable attentions as efficient catalysts because of their relatively strong Brönsted acidity of oxygen‐ and sulfur‐containing functional groups together with the green, convenient and stable natures .…”

“…However, the aforementioned studies on carbonaceous solid acids have been conducted to a lesser extent. Therefore, the synthesis of carbon‐based solid acid with tunable surface acid sites might be the appropriate candidate for the production of 5‐HMF from fructose under aqueous conditions or in biphasic (aqueous/organic) systems with high 5‐HMF yields …”

“…After large‐scale productions of biogas, biobutanol, bioethanol etc from microalgae, amounts of defatted microalgae residue remains and has always been discarded as waste. Normally, the remnant biodiesel waste is notably rich in algal carbohydrates, proteins etc, which indicates that microalgae residue might be a potential bio‐resource for preparing carbon catalysts owing to its low cost and easy sustainability ,. Accordingly, it could be an active research topic to exploit the waste microalgae residue, as well as to utilize this waste residue to produce staple or value‐added platform chemicals.…”

An Excellent Solid Acid Catalyst Derived from Microalgae Residue for Fructose Dehydration into 5‐Hydroxymethylfurural

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.
