“…75 Both CMK-3 and CMK-5 showed good catalytic stability compared with acidfunctionalised SBA-15 and commercial Nafion SAC-13 catalysts. Zhang et al 150 developed an efficient mesoporous carbon-based solid acid using ethylene tar and concentrated H 2 SO 4 with magnesium acetate as the template. A 87.8% yield of HMF was obtained via fructose dehydration, attributed to superior specific surface area and higher concentration of sulfonic acid groups in the developed mesoporous carbon catalyst.…”

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.

“…As an alternative, covalent organic frameworks (COFs) with welldefined pores and binding sites are promising for the adsorptive removal of various inorganic and organic pollutants. 25−28 In particular, imine-based 2D COFs are used for several applications such as gas adsorption, separation 29 and storage, 30,31 molecular separation, 32,33 sensing, 34,35 heterogeneous catalysis, 36,37 organocatalysis, 38,39 and electrocatalysis, 40,41 for their pore tunability and stability. As a worthwhile choice for sequestering charged pollutants, ionic covalent organic frameworks (iCOFs) have emerged as a superior class of adsorbents.…”

Water contamination by inorganic and organic pollutants is one of the most contentious global environmental issues. However, conventional scavenging materials often exhibit poor selectivities and limited adsorption capabilities. By contrast, an ionic covalent organic framework (iCOF) with functionalized pores promises effective capture of harmful oxo-anions and carcinogenic dyes and can benefit their removal over a practical platform. We employ facile Schiff base condensation to devise a thermochemically robust guanidinium-based iCOF via the incisive amalgamation of anion exchange, hydrogen bonding, and electrostatic interaction sites. Building on such trifunctionality, the material demonstrates efficient sequestration of dichromate oxoanions and Congo Red (CR) dye in water with rapid kinetics and superior scavenging capacity (Cr 2 O 7 2− : 412 mg/g, CR: 316.3 mg/ g) compared to other porous crystalline materials. Apart from the high selectivity in the presence of interfering anions/dyes, the adsorptive capacities remain unaltered (>90%) for five cycles with postrelease stability. In-depth analysis corroborates that the removal of oxo-anions is driven by the ion-exchange phenomena, while electrostatic, hydrogen bonding, and π−π stacking interactions play a role in dye adsorption, as also supported by density functional theory studies. The real-time potential of iCOF for long-term water purification has been established via the fabrication of a polysulfone (PSF)-based mixed-matrix membrane. The iCOF@PSF ultrafiltration membrane exhibits high water permeance and rejection of both dichromate (87%) and CR (99.9%) with excellent recyclability. Notably, a high permeate flux of the iCOF@PSF membrane for dichromate (88.6 ± 1.8 L/m 2 h bar) and CR dye (86.2 ± 1.5 L/m 2 h bar) validate effective synergism between iCOF functionalities and the PSF matrix in sieving both the anionic pollutants and provide valuable insights into the development of porous charged materials for wastewater remediation over a practical platform.

Lignocellulose is a key starting material for the production of biofuels, biochemicals, and biomaterials. This review discusses various catalytic systems, including homogeneous and heterogeneous catalytic systems, for biomass valorization. Different strategies of biomass‐derived catalyst systems for value‐added chemicals are evaluated. Novel strategies for using biomass‐derived carbon‐based catalysts are proposed as a potential way to make the valorization process economically viable. This review also provides a comprehensive assessment of the fabrication of biomass‐derived carbon as catalytic support for biorefinery applications and discussion about mechanism of the synergistic catalytic effect between the biochar and catalyst. © 2021 Society of Chemical Industry and John Wiley & Sons, Ltd
