Carbon dioxide (CO₂) has attracted great interest as a catalyst and reaction medium for the conversion of lignocellulosic biomass into value-added commodity chemicals. In this review, we focus on the use of CO₂ in the pretreatment of raw biomass (for example, to isolate sugar monomers from the polymeric components of lignocellulosic biomass) and subsequent hydrolysis, as well as in different reactions to yield valuable platform chemicals from feedstocks derived from the raw biomass (e.g., dehydration, hydrogenation, and hydrodeoxygenation). In this respect, this review gives a summary of the enhancement in biomass conversion reactions achievable by utilizing CO₂ and the roles of CO₂ in this enhancement. Recent achievements (mostly in the past five years) in CO₂-catalyzed and CO₂-assisted biomass conversion reactions in various systems are highlighted. The prospect of transforming biomass feedstocks to platform chemicals using CO₂ is also discussed, and important points and challenges facing further research into the CO₂-driven conversion of biomass are highlighted.

二氧化碳辅助和二氧化碳催化的生物质转化反应的最新成就

二氧化碳（CO ₂）作为将木质纤维素生物质转化为增值商品化学品的催化剂和反应介质引起了极大的兴趣。在这篇综述中，我们着重于在原始生物质的预处理中使用CO ₂（例如，从木质纤维素生物质的聚合物成分中分离糖单体）和随后的水解，以及在不同的反应中从中获得有价值的平台化学品源自原始生物质的原料（例如，脱水，氢化和加氢脱氧）。在这方面，这条给出了增强的生物质转化反应达到的概要通过利用CO ₂和CO的角色₂在此增强中。着重介绍了在各种系统中在CO ₂催化和CO ₂辅助生物质转化反应方面的最新成就（大部分是在过去的五年中）。还讨论了使用CO ₂将生物质原料转化为平台化学品的前景，并着重指出了进一步研究CO ₂驱动的生物质转化所面临的重点和挑战。
