Amine-functionalized MOF membranes via microwave/ultrasonic heating for catalytic applications

초록

Metal organic frameworks (MOFs) are a class of organic-inorganic hybrid materials composed of metal clusters interconnected through a rigid organic linker. In this work, continuous and defect-free IRMOF-3(Zn) and MIL125-NH2 (Ti) membranes supported on either Al2O3 and TiO2 (both on a TiO2 disc and on TiO2 nanotubes obtained by anodization), relatively, were prepared by ultrasonic (US) and microwave (MW) heating methods, and the obtained membranes were applied as a heterogeneous catalyst for the Knoevenagel condensation reaction with high stability and recyclability, which enabled easy catalyst separation in liquid phase.
