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.

“…Owing to its instability, 5‐HMF requires careful tuning of the reaction parameters and/or a continuous extraction process to ensure high yields. The instability of 5‐HMF and the possibility of forming humins and other side products often leads to modest yields, which typically range from 20 to 70 % . Here, the yield of 5‐HMF was determined by 1 H NMR spectroscopy with CH 2 Br 2 as internal standard, and the identity of the product was further confirmed by GC‐MS (see Experimental Section and Figures S6–S9 for representative 1 H NMR spectra).…”

“…Actually, the conversion of glucose into 5-HMF is a crucial intermediate step for cellulose being converted to 5-HMF. Considering the convenient separation of a catalyst from the mixture, a magnetic solid acid Fe 3 O 4 @SiO 2 /PHA was prepared by phosphotungstic acid (Brønsted acid) supported on magnetic nanoparticles (Fe 3 O 4 ) coated by SiO 2 ( Figure 11 ) ( Wang Y. et al, 2019 ). The magnetic solid acid in possession of good recovery by an external magnet could be on the run for four cycles in the glucose conversion to 5-HMF, without catalytic activity declining significantly.…”

5-Hydroxymethylfurfural (5-HMF) as a triply catalytic product is a value-added refining chemical in industry production. 5-HMF as biomass feedstock enables to be transformed into other high-value industrial compounds, such as 2,5-furandicarboxylic acid (FDCA), 5-hydroxymethyl-2-furancarboxylic acid (HMFCA), 5-formyl-2-furancarboxylic acid (FFCA), 2,5-diformylfuran (DFF), 2,5-bis(aminomethyl)furan (BAMF), and 2,5-dimethylfuran (DMF). Hence, catalytic conversion of biomass into 5-HMF has been given much more attention by chemists. In this review, some latest studies about the conversion of cellulose to 5-HMF have been introduced systematically. Solid acids such as heterogeneous catalysts have been widely applied in the conversion of cellulose into 5-HMF. Therefore, some novel solid acids with Brønsted and/or Lewis acidic sites, such as sulfonated solid acids, carbon-based acids, and zeolite particles employed for biomass conversions are listed.
