Bio‐refinery is attracting significant interest to produce a wide range of renewable chemicals and fuels from biomass that are alternative to fossil fuel derived petrochemicals. Similar to petrochemical industries, bio‐refinery also depends on solid zeolite catalysts. Acid‐base catalysis plays pivotal role in producing a wide range of chemicals from biomass. Herein, the Mg framework substituted MTW zeolite is synthesized and explored in the valorisation of glucose and furfural. Bi‐functional (acidic and basic) characteristics are confirmed using pyridine adsorbed FT−IR analysis and NH₃ and CO₂ temperature‐programmed desorption techniques. Textural properties and morphological information are retrieved from N₂‐sorption, X‐ray photoelectron spectroscopy, and electron microscopy. The activity of the catalyst is demonstrated in the selective isomerisation of glucose to fructose in ethanol. Glucose is converted to methyl lactate in high yield using the same catalyst. Further, the bi‐functional activity of this catalyst is demonstrated in the production of fuel precursor by the reaction of furfural and isopropanol. Mg−MTW zeolite exhibits excellent activity in the production of all these chemicals and fuel derivative. The catalyst exhibits no significant loss in the activity even after five recycles. One simple catalyst affording three renewable synthetic intermediates from glucose and furfural will attract significant attention to catalysis researchers and industrialists.

双功能硅酸镁催化葡萄糖和糠醛向可再生化学品的转化

生物炼制吸引了人们广泛的兴趣，他们希望利用生物质来生产各种各样的可再生化学物质和燃料，以替代化石燃料衍生的石油化学物质。与石化行业类似，生物炼油厂也依赖于固体沸石催化剂。酸碱催化在由生物质生产各种化学品中起着关键作用。在此，合成并探索了Mg骨架取代的MTW沸石，用于葡萄糖和糠醛的增值。使用吡啶吸附的FT-IR分析以及NH ₃和CO _2程序升温脱附技术证实了双功能（酸性和碱性）特性。从N ₂检索纹理特性和形态信息吸收，X射线光电子能谱和电子显微镜。在乙醇中葡萄糖选择性异构化为果糖中证明了催化剂的活性。使用相同的催化剂将葡萄糖高产率地转化为乳酸甲酯。此外，通过糠醛和异丙醇的反应在燃料前体的生产中证明了该催化剂的双功能活性。Mg-MTW沸石在所有这些化学物质和燃料衍生物的生产中均表现出出色的活性。即使经过五次循环，该催化剂也没有表现出明显的活性损失。一种可以从葡萄糖和糠醛提供三种可再生合成中间体的简单催化剂将引起催化研究人员和工业家的极大关注。
