近日,武汉大学定明月教授团队报道了含氮MOFs螯合稳定动态单原子Cu催化剂,MOF中含氮有机配体可以作为钳子来螯合和稳定客体Cu原子,MOF的精确空间限域和原子级分散Cu物种赋予了其在反应物吸附和产物脱附过程中Cu-N键可逆断裂的动态效应,促进了中间产物选择性吸附及产物的快速脱附,实现了HMF定向高效、高选择性加氢。相关研...
MOF-808(Zr) has tunable active sites and excellent stability under high temperatures and acidic as well as basic environments, and the unsaturated coordination of metal ions within its framework structure can exhibit Lewis acidity, facilitating catalytic transfer hydrogenation from HMF to 2,...

Here, we purposely developed a Cu(II) porphyrin framework featuring side‐chain incorporated urea linkages, denoted as TBUPPCu MOF, to render HMF a weak hydrogen bond at the urea site and flat adsorption via π–π stacking with the benzene moiety. The unique configuration...
The method of preparing the MOF membrane or zeolite membrane using an organosiloxane agent modified base has been previously reported [36–40]. The XRD shows that the prepared Cu3(BTC)2 membrane has an intact morphology with its crystal, and the SEM shows that it is continuous, compact, ...
