葡萄糖异构化为果糖是木质纤维素通过糖平台生化转化为液体燃料和化学品的关键中间步骤。本研究展示了制备葡萄糖在水中异构化为果糖的非均相或磁性碱催化剂的简便和通用的策略。多相或磁性碱催化剂可以获得与均相有机碱催化剂相似的葡萄糖转化为果糖的产率和选择性。副产物的积累影响多相碱催化剂的重复使用，而磁化碱催化剂表现出良好的稳定性和重复使用性。
Isomerization of glucose to fructose is a key intermediate step for the biochemical conversion of lignocellulose to liquid fuels and chemicals through the sugar platform. This study demonstrates facile and general strategies to fabricate heterogeneous or magnetic base catalysts based on organic bases for the isomerization of glucose to fructose in water. The heterogeneous or magnetic base catalyst can achieve similar glucose-to-fructose yield and selectivity to homogenous organic base catalyst. The accumulated by-products influence the reusability of the heterogeneous base catalyst; however, the magnetic base catalyst shows excellent stability and reusability.
