(NH₄)₅H₆PV₈Mo₄O₄₀ supported on hydroxyapatite (HAP) (PMo₄V₈/HAP (n)) was prepared through the ion exchange of hydroxy groups. This ion exchange favored the oxidative conversion of 5-hydroxymethylfurfural (5-HMF) to 2,5-diformylfuran (DFF) in a one-pot cascade reaction with 96.0 % conversion and 83.8 % yield under 10 mL/min of O₂ flow. PMo₄V₈/HAP (31) was used to explore the production of DFF directly from glucose with the highest yield of 47.9 % so far under atmospheric oxygen, whereas the yield of DFF increased to 54.7 % in a one-pot and two-step reaction. These results indicated that the active sites in PMo₄V₈/HAP (31) retained their activities without any interference toward one another, which enabled the production of DFF in a more cost-saving way by only using oxygen and one catalyst in a one-step reaction. Meanwhile, the rigid structure of HAP and strong interaction in PMo₄V₈/HAP (31) allowed this catalyst to be reused for at least six times with high stability and duration.

羟基磷灰石负载的多金属氧酸盐在大气压下高选择性有氧氧化 5-羟甲基糠醛或葡萄糖生成 2,5-二甲酰呋喃

通过羟基离子交换制备负载羟基磷灰石(HAP)的(NH ₄ ) ₅ H ₆ PV ₈ Mo ₄ O ₄₀ (PMo ₄ V ₈ /HAP(n))。这种离子交换有利于在一锅级联反应中将5-羟甲基糠醛（5-HMF）氧化转化为2,5-二甲酰呋喃（DFF），在10 mL/min的O ₂流量下，转化率达到96.0%，产率达到83.8%。利用 PMo ₄ V ₈ /HAP (31) 探索了在常压氧气下直接从葡萄糖生产 DFF 的产率，迄今为止最高产率为 47.9%，而一锅法和两锅法中 DFF 的产率提高到 54.7%。步反应。这些结果表明，PMo ₄ V ₈ /HAP (31) 中的活性位点保留了其活性，彼此之间没有任何干扰，这使得仅使用氧气和一种催化剂即可以一种更节省成本的方式生产 DFF。步反应。同时，HAP的刚性结构和PMo ₄ V ₈ /HAP (31)中的强相互作用使得该催化剂可以重复使用至少六次，并且具有高稳定性和持久性。
