The selective conversion of furfural (FUR) with ethanol to produce furan-2-acrolein has been successfully performed in the presence of O₂, in which metal organic framework (MOF) supported platinum nanoparticles (Pt@MOF-5, Pt@UIO-66, and Pt@UIO-66-NH₂) were used as the catalysts. Under the optimal conditions, 84.1% conversion of FUR and 90.1% selectivity of furan-2-acrolein was obtained with Pt@MOF-5 as the catalyst. Moreover, the catalysts were characterized by XRD, H₂-TPR, HRTEM, HRSEM, and XPS techniques, with the synergetic effect of well-dispersed platinum nanoparticles in the MOF-5 channel. In addition, the results of the recycling experiment exhibited that there was no significant loss after the catalyst was reused 5 times.

Pt @ MOF-5介导的可再生糠醛与乙醇的选择性转化制备呋喃-2-丙烯醛

在O ₂存在下成功地进行了糠醛（FUR）与乙醇的选择性转化以生成呋喃-2-丙烯醛，其中金属有机骨架（MOF）负载了铂纳米颗粒（Pt @ MOF-5，Pt @ UIO-使用Pt @ UIO-66-NH _2（ 66，和PtUU-66-NH ₂）作为催化剂。在最佳条件下，以Pt @ MOF-5为催化剂，可获得84.1％的FUR转化率和90.1％的呋喃-2-丙烯醛选择性。此外，通过XRD，H ₂ -TPR，HRTEM，HRSEM和XPS技术对催化剂进行了表征，并在MOF-5通道中充分分散了铂纳米粒子的协同作用。另外，循环实验的结果表明，催化剂重复使用5次后，没有明显的损失。
