Catalytic application of molybdenum disulfide (MoS₂) for the production of high-value chemicals from the lignocellulosic biomass is investigated for the first time. In particular, the synthesis of 5-ethoxymethylfurfural (EMF), and 5-hydroxymethylfurfural (HMF) from biomass-derived resources in the presence of inexpensive and readily available MoS₂ catalyst via microwave-assisted heating has been studied. The experiments were performed at 100 to 160 °C temperature for 2 to 30 min reaction time in a microwave reactor. Accordingly, the experimental conditions such as reaction temperature, reaction time, catalyst concentration, and feed concentration were optimized for the maximum yield of EMF from the fructose. As a result, maximum 93.3 mol% EMF yield was measured at 160 °C reaction temperature in 30 min when experiments were performed in the presence of 0.3 mmol MoS₂ for fructose conversion. It was also observed that the molybdenum disulfide selectively produces EMF in a higher amount with negligible byproducts under optimum operating conditions. Post this, a range of alcohols such as methanol, 1-propanol, 1-butanol, and 1-pentanol were tested for the production of different alkoxymethylfurfurals, which showed more than 95% fructose conversion in all cases. Similarly, a wide range of substrates such as glucose, galactose, mannose, and cellulose were tested, which resulted in significant production of EMF. Notably, the EMFs obtained from the experiments can be used as a precursor to producing a vast range of chemicals like polymers, fragrance, plasticizer, resins, fuel additives, and fuel.

首次研究了二硫化钼（MoS ₂）催化从木质纤维素生物质生产高价值化学品的应用。特别地，在廉价且容易获得的MoS ₂存在下，由生物质衍生资源合成5-乙氧基甲基糠醛（EMF）和5-羟甲基糠醛（HMF）。已经研究了通过微波辅助加热的催化剂。实验是在微波反应器中于100至160℃的温度下进行2至30分钟的反应时间。因此，为了从果糖中获得EMF的最大产率，优化了实验条件，例如反应温度，反应时间，催化剂浓度和进料浓度。结果，当在0.3 mmol MoS ₂的存在下进行实验时，在160°C反应温度下30分钟内测得的最大93.3 mol％EMF产率。用于果糖转换。还观察到，在最佳操作条件下，二硫化钼有选择地产生较高数量的EMF，副产物可忽略不计。此后，测试了一系列醇（例如甲醇，1-丙醇，1-丁醇和1-戊醇）用于生产不同的烷氧基甲基糠醛，在所有情况下果糖转化率均超过95％。类似地，测试了各种底物，例如葡萄糖，半乳糖，甘露糖和纤维素，这导致产生大量EMF。值得注意的是，从实验中获得的EMF可用作生产多种化学品（如聚合物，香料，增塑剂，树脂，燃料添加剂和燃料）的前体。
