生物质被视为一种潜在的丰富可再生能源,可用于生产能源、化学品和材料等,是传统能源的潜在替代品。5-羟甲基糠醛(5-hydromethylfurfural,HMF)是一种多功能、关键的可再生平台化合物,有许多潜在的应用,被誉为“沉睡的巨人”,可以由生物质衍生的碳水化合物生产。目前,制备HMF的原料主要是糖类化合物。深入讨论了HMF的合成机理以及己糖、多糖和其他生物质等不同来源的原料催化制备HMF方法的研究进展。以往的研究可以发现,葡萄糖转化为HMF大多选用路易斯酸催化剂,对于果糖则更注重于非均相催化剂的设计。多糖类最终水解为单糖进行转化,应同时注重多糖的水解以及单糖的转化,关键点仍是单糖的转化。最后对HMF原料未来的研究方向和催化剂的设计开发进行展望,以期为今后的深入研究提供理论支持。

Biomass is widely recognized as a potentially abundant source of renewable energy, chemi cals, materials, and more, making it an excellent alternative to traditional energy sources. 5-hydroxy methylfurfural ( 5 - HMF), also known as HMF, is a versatile and critical renewable platform compound. It has earned the nickname " sleeping giant" due to its vast range of potential applications that can be derived from biomass-derived carbohydrates. Currently, saccharides serve as the primary raw materials for HMF preparation. In this paper, we delve into the mechanism of HMF synthesis and discuss the research progress on the catalytic preparation of 5-HMF from various feedstock sources, in cluding hexoses, polysaccharides, and other biomasses. Previous studies indicate that the presence of metal elements can enhance the conversion rate of glucose, whereas for fructose, the focus lies more on designing a non-homogeneous catalyst to improve the yield. The hydrolysis of polysaccharides into mon osaccharides is a crucial step for conversion, emphasizing both polysaccharide hydrolysis and monosac charide conversion. Finally, we provide an outlook on the future research direction of HMF feedstocks, as well as the design and development of catalysts, aiming to offer theoretical support for future in depth research.
