Supported Metal Organic Frameworks (MOFs) with a high specific surface area are of great interest for applications in gas storage, separation, sensing, and catalysis. In the present work we report the synthesis of a novel composite architecture of MOF materials supported on a flexible mat of electrospun nanofibers. The system, based on three-dimensional interwoven nanofibers, was designed by using a low-cost and scalable multistep synthesis protocol involving a combination of electrospinning and low-temperature atomic layer deposition of oxide materials, and their subsequent solvothermal conversion under either conventional or microwave-assisted heating. This highly versatile approach allows the production of different types of supported MOF crystals with controlled sizes, morphology, orientation and high accessibility.
具有高比表面积的负载型金属有机骨架（MOFs）在气体存储、分离、传感和催化等应用中具有重要意义。在本工作中，我们报道了一种新型 MOF 材料负载在柔性电纺纳米纤维毡上的复合材料结构的合成。该体系基于三维交织纳米纤维，通过使用低成本和可扩展的多步合成方案设计，该方案涉及电纺丝和低温原子层沉积氧化物材料的组合，以及随后在常规或微波辅助加热下进行溶剂热转化。这种多功能方法可以生产不同类型的负载型 MOF 晶体，具有可控的尺寸、形态、取向和高可及性。
