Abstract

Constructing hierarchically ordered pore MOFs (HP MOF) are attracting more and more attentions because of the improved mass diffusion and transport kinetics. However, most of the reported HP MOFs are three-dimensional morphologies. The fabrication of two-dimensional HP MOF membrane is still challenging, because of the significant disturbance caused by the adding solvent to the assembled templates. Herein, combined soft spray technology with template-assisted strategy, two different kinds of HP ZIF-8 and HP ZIF-8/PVA membranes were fabricated by changing the reaction solution. The prepared HP ZIF-8 membranes had high crystallinity, hierarchically ordered pore size and two-dimensional morphology, which exhibited potential applications in organic catalysis and emulsion separation.

用软喷法制备的有序孔金属有机骨架膜

由于质量扩散和输运动力学的改善，构建分层有序孔MOF （HP MOF）越来越受到人们的关注。然而，大多数报道的HP mof都是三维形态的。由于在组装模板中加入溶剂会引起明显的干扰，制备二维HP MOF膜仍然具有挑战性。本文将软喷涂技术与模板辅助策略相结合，通过改变反应溶液制备了两种不同类型的HP ZIF-8和HP ZIF-8/PVA膜。制备的HP ZIF-8膜具有较高的结晶度、有序的孔隙大小和二维形态，在有机催化和乳液分离方面具有潜在的应用前景。

期刊介绍： Microporous and Mesoporous Materials covers novel and significant aspects of porous solids classified as either microporous (pore size up to 2 nm) or mesoporous (pore size 2 to 50 nm). The porosity should have a specific impact on the material properties or application. Typical examples are zeolites and zeolite-like materials, pillared materials, clathrasils and clathrates, carbon molecular sieves, ordered mesoporous materials, organic/inorganic porous hybrid materials, or porous metal oxides. Both natural and synthetic porous materials are within the scope of the journal. Topics which are particularly of interest include: All aspects of natural microporous and mesoporous solids The synthesis of crystalline or amorphous porous materials The physico-chemical characterization of microporous and mesoporous solids, especially spectroscopic and microscopic The modification of microporous and mesoporous solids, for example by ion exchange or solid-state reactions All topics related to diffusion of mobile species in the pores of microporous and mesoporous materials Adsorption (and other separation techniques) using microporous or mesoporous adsorbents Catalysis by microporous and mesoporous materials Host/guest interactions Theoretical chemistry and modelling of host/guest interactions All topics related to the application of microporous and mesoporous materials in industrial catalysis, separation technology, environmental protection, electrochemistry, membranes, sensors, optical devices, etc.
