The use of carbon-based catalysts to catalyze the hydrothermal conversion of biomass and its derived carbohydrates to produce platform compounds such as 5-(hydroxymethyl)furfural (HMF), levulinic acid (LA), and furfural (FF) has a long history. The excellent thermal stability and chemical activity and low preparation cost of carbon-based catalysts make them develop rapidly in catalytic hydrothermal conversion, which is the core attention in the review. Carbon catalysts are divided into sulfuric acid-based carbon catalysts, phosphoric acid-based carbon catalysts, metal-supported carbon catalysts and other types of carbon catalysts, to study their application to hydrothermal decomposition of monosaccharides, disaccharides, polysaccharides, and biomass. The characteristics of different types of carbon catalysts were introduced. The diversified development of carbon-based catalysts and the upgrading of feedstocks have promoted the improvement of product selectivity, cost, and energy optimization, realizing the transformation of hydrothermal decomposition of biomass into a greener process. However, the development of efficient catalytic systems for hydrothermal conversion of abundant, cheap, and readily available biomass sources is still an ideal choice to expand the process strategy.

通过碳基固体酸催化剂水热转化从生物质或糖类制备平台化合物的批判性评论
使用碳基催化剂催化生物质及其衍生碳水化合物的水热转化以生产平台化合物，如 5-（羟甲基）糠醛（HMF）、乙酰丙酸（LA）和糠醛（FF）具有悠久的历史。碳基催化剂优异的热稳定性和化学活性以及低廉的制备成本，使其在催化水热转化方面得到迅速发展，是本综述的核心关注点。碳催化剂分为硫酸基碳催化剂、磷酸基碳催化剂、金属负载碳催化剂和其他类型的碳催化剂，研究它们在单糖、双糖、多糖和生物质水热分解中的应用。介绍了不同类型碳催化剂的特点。碳基催化剂的多元化发展和原料的升级，促进了产品选择性、成本和能源优化的提高，实现了生物质水热分解向更绿色工艺的转变。然而，开发用于水热转化丰富、廉价且容易获得的生物质资源的高效催化系统仍然是扩展工艺策略的理想选择。
