Aiming at the highly selective production of 2,5-dimethylfuran (DMF) from fructose, a one-pot strategy and bifunctional catalysts with different surface wettability were specially designed. The hydrophobic surface assisted in weakening side reactions and promoting the adsorptive property for the hydrogen donator. The as-prepared Pd/PDVB-S-143 catalyst showed high activity and good stability: Yield of 94.2% was obtained under mild reaction conditions, and no loss in activity was observed after 5 cycles. From the standpoint of green and sustainable chemistry, there may be several possible advantages. HMF separation is avoided, reducing the amount of organic solvent and energy expenditure for purifying HMF; besides, polymethylhydrosiloxane (PMHS) was used as the hydrogen source, increasing the convenience and efficiency of the whole process. Overall, this work demonstrates a successful strategy for rational design and preparation of novel catalysts with both high activity and superior selectivity during biomass upgrading.

通过定制催化剂润湿性从果糖中选择性生产2，5-二甲基呋喃

针对由果糖高选择性生产2，5-二甲基呋喃（DMF）的问题，专门设计了一种锅法和具有不同表面润湿性的双功能催化剂。疏水表面有助于减弱副反应并提高对氢供体的吸附性能。所制备的Pd / PDVB-S-143催化剂显示出高活性和良好的稳定性：在温和的反应条件下产率为94.2％，并且在5个循环后没有观察到活性损失。从绿色和可持续化学的角度来看，可能有几个优点。避免了HMF分离，减少了纯化HMF所需的有机溶剂量和能源消耗；另外，使用聚甲基氢硅氧烷（PMHS）作为氢源，增加了整个过程的便利性和效率。全面的，
