摘要

探索将碳水化合物转化为有价值的化学品,为利用可再生生物质资源提供了一种前景广阔、生态友好的方法。在这一直接转化过程中,开发一种双功能、可持续的异相催化剂对于实现所需产物 2,5-二甲酰呋喃(DFF)的高选择性至关重要。在这项研究中,我们开发了一种高效催化系统,可将多种碳水化合物转化为 DFF。我们的方法包括利用一种 MoS2 催化剂,该催化剂由从磺化甘蔗生物质中提取的无定形碳支撑。MoS2@SBG-SO3H 复合材料采用简便、高效的方法成功合成。通过脱水和氧气氧化一步法和一锅反应,果糖在 160 °C、5 小时内转化为 DFF 的收率高达 70%。使用 MoS2@SBG-SO3H 将 5-hydroxymethylfurfural (HMF) 氧化成 DFF,5 h 内的 DFF 收率达到 94%;活化能为 38.3 kJ.mol-1。该催化剂易于回收和重复使用。从各种碳水化合物(如蔗糖、葡萄糖、麦芽糖和乳糖)直接合成 DFF 的产率很高。我们的研究为制备碳基固体酸催化剂和 DFF 提供了一种快速、绿色和高效的工艺。

One-Pot Effective Approach to 2,5-Diformylfuran From Carbohydrates Using MoS2-Decorated Carbonaceous Sugarcane Bagasse

Exploring the transformation of carbohydrates into valuable chemicals offers a promising and eco-friendly method for utilizing renewable biomass resources. Developing a bi-functional, sustainable heterogeneous catalyst is of utmost importance to attain a high level of selectivity for the desired product, 2,5-diformylfuran (DFF), in this direct conversion process. In this study, we developed a highly effective catalytic system to convert diverse carbohydrates into DFF. Our approach involved utilizing a MoS2 catalyst supported by amorphous carbon derived from sulfonated sugarcane biomass. The MoS2@SBG-SO3H composite was successfully synthesized using a facile and highly efficient method. The transformation of fructose into DFF achieved a significant yield of 70 % for 5 h at 160 °C using a one-step and one-pot reaction through dehydration and oxidation with oxygen. The oxidation of 5-hydroxymethylfurfural (HMF) into DFF using MoS2@SBG-SO3H was obtained at 94 % DFF within 5 h; the activation energy was 38.3 kJ . mol−1. The catalyst displayed convenient recovery and reusability. The direct synthesis of DFF from various carbohydrates, such as sucrose, glucose, maltose, and lactose, resulted in favorable yields. Our research provides a quick, green, and efficient process for preparing carbon-based solid acid catalysts and DFF.
