摘要:低共熔溶剂（Deep Eutectic Solvents，DESs）由于具有熔点低、溶解性好、制备成本低、绿色无毒、可生物降解和电化学窗口宽等特性而被视为新型绿色溶剂，在木质纤维生物质预处理领域展现出广阔的应用前景。本文综述了DESs在预处理木质纤维生物质、制备纳米纤维素、高效提取分离木质素与半纤维素领域的研究进展，并指出了DESs在目前研究发展中存在的不足及其未来的研究方向，以期为进一步研究提供理论依据。

Abstract:Deep Eutectic Solvents （DESs） are considered as new green solvents with low melting point， good solubility， low preparation cost， green and non-toxicity， biodegradability， and wide electrochemical window. It shows a broad application prospect in the field of lignocellulosic biomass pretreatment. In this study， the research progress of DESs in the fields of pretreatment of lignocellulosic biomass， preparation of nanocellulose and efficient extraction and isolation of lignin and hemicellulose were reviewed， and the shortcomings of DESs in the current research progress and their future research directions were pointed out to provide a theoretical basis and reference for further research.
