(381s) Preparation and Application of Ceramic-Supported Metal-Organic Framework Membranes

Membrane-based separation outperforms other techniques for separation of matters at molecular level because of its low cost, energy saving potential, high capacity, continuous operation and easy scale-up, but raise high requirements for the membrane materials. Recently, metal-organic frameworks (MOFs) have attracted great attention in many fields because of their large surface areas, chemically functionalized cavities, flexible skeletons, and intriguing electronic properties. These unique features make them excellent candidates for applications in membrane separation fields. Herein, based on ceramic supports (ceramic disc and hollow fiber), a series of MOF membranes, including Zn-CD, ZIF-8, ZIF-71 and UiO-66 membranes, were successfully prepared and showed good separation performance in gas and liquid separation field.
