A promising atom-effective heterogeneous catalyst derived from the partial carbonization of polyoxometalate based mesoporous poly(ionic liquid) was constructed for the direct (one-pot and one-step) conversion of carbohydrates into 2,5-diformylfuran (DFF). The carbon precursor was synthesized through the free radical copolymerization of carboxylic acid functional ionic liquid and divinyl benzene, followed by the ion-exchange with heteropolyacid H₅PMo₁₀V₂O₄₀ to introduce heteropolyanions. Partial carbonization dramatically enhanced the acid and oxidation properties, rendering the greatly strengthened activity in both the degradation of fructose into 5-hydroxymethylfurfural (HMF) and oxidation of HMF into DFF. As a result, the catalyst exhibited remarkable performance in the direct synthesis of DFF from fructose in a one-pot and one-step reaction, offering a high yield of 87.3% and a maximum turnover number (TON) of 77.7. The catalyst was facilely recovered and reused without apparent deactivation. The one-pot and one-step conversion of glucose into DFF reached the highest yield of 51.2% so far. Other carbohydrates such as inulin and sucrose were also effectively transformed into DFF, displaying good substrate compatibility.

从多金属氧酸盐基介孔聚离子液体的部分碳化衍生出了一种有希望的原子有效的多相催化剂，用于将碳水化合物直接（一锅一步地）转化为2,5-二甲酰呋喃（DFF）。碳前驱物是通过羧酸官能离子液体和二乙烯基苯的自由基共聚反应，然后与杂多酸H ₅ PMo ₁₀ V ₂ O ₄₀进行离子交换而合成的。引入杂多阴离子。部分碳化极大地增强了酸和氧化性能，使果糖降解为5-羟甲基糠醛（HMF）和将HMF氧化为DFF的活性大大增强。结果，该催化剂在由一锅一步反应由果糖直接合成DFF中显示出显着的性能，提供了87.3％的高收率和77.7的最大周转数（TON）。催化剂容易回收并重新使用而没有明显的失活。到目前为止，一锅一步将葡萄糖转化为DFF的最高收率达到51.2％。其他碳水化合物（例如菊粉和蔗糖）也有效地转化为DFF，表现出良好的底物相容性。
