Abstract:The complexity and recalcitrance of lignocellulosic biomass seriously hinder’s its subsequent conversion to liquid fuels. To achieve high-value utilization of lignocellulosic biomass, the physical-chemical barrier should be overcome through appropriate...
“…[7][8][9] Biomass processing solvents including organic solvents, aqueous phase hydrotropes, and ionic liquids have been investigated to understand their effectiveness and fundamental mechanisms for biomass fractionation. [10][11][12][13][14][15][16][17][18][19][20][21] In addition to the technical performance of these solvents, their economic feasibility and environmental sustainability have been evaluated and considered in recent studies. 22,23 Despite many efforts in studying these solvent systems, many technical barriers remained to be overcome for commercialization.…”
Hydrotropic solvents are a promising solvent in biomass processing due to their unique amphiphilic structure. This review summarizes recent advances in hydrotropic solvent systems with their chemical structure, amphiphilicity, roles, and mechanism.

“…[16][17][18] The physical stabilization strategy, which involves the prompt separation of active reaction products, has shown great potential in controllable biorefinery. [19][20][21] The development of biphasic solvent systems plays a crucial role in enabling tailored lignocellulose fractionation, lignin extraction, and carbohydrate transformation processes. [22][23][24][25] For example, Chen et al provided a comprehensive overview of various biphasic solvent systems comprising organic solvents and water for biomass fractionation.…”
Solvents with integrated functions enable directional lignin valorization for producing value-added chemicals or lignin polyols. In this study, a solvent-triggered directional lignin valorization was developed based on the design of...
“…[20][21][22][23][24]25 Owing to their good solvation ability, DESs have been utilized in various processes such as biomass processing, organic synthesis, materials science, extraction and separation. 26 Considering these applications, Zhang et al, used a DES as a medium for preparing covalent organic framework (COF) materials with imine linkages. The copper metal was immobilized on COFs for enhancing photocatalytic applicability.…”
Relatively greener methods for the direct and single-step conversion of abundantly available biomass into oxidized graphitic material should be developed for promoting the utilization of such materials in different applications....
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
