ZeoMOFs

在这个项目中，我们建议开发一种全新的混合材料，包含沸石和金属有机框架（MOF）的区域-我们称这些材料为ZeoMOF。微孔材料，包括沸石和MOFs，构成了当前研究中最重要的一类材料：沸石在工业中大量使用，MOFs是过去二十年来制备的最令人兴奋的材料之一。虽然它们的结构架构看起来相似（两种类型的材料都是多孔的），但它们的化学性质却截然不同。这意味着部分沸石和部分MOF的材料无疑具有一些非常有趣的特性。然而，由于其合成条件的不相容性，使用传统方法合成这种紧密的ZeoMOF杂合体是困难的，并且可能是不可能的。这意味着我们必须设计一种新的方法。在这个项目中，我们将开发一些最近的合成工作，我们已经完成了在该地区的操纵结构使用ADOR过程。在这个项目中，我们将使用这些最新的发展，首先制备沸石层。然后在沸石层保持稳定的仔细控制的条件下，我们使用MOF合成中使用的“更软”条件将MOF物质插入沸石层之间并将它们连接在一起。最初制备的材料可能是无序的，但随着我们获得必要的化学经验，我们期望制备更多的结晶多孔固体。这些材料将具有挑战性，我们将使用散射和磁共振（和其他）技术的组合来充分了解材料的结构，然后我们将完成一项旨在了解新固体性质的活动，特别关注确定与沸石和MOF相比，孔隙率，催化和吸附（例如用于分离）性质如何改变。

In this project, we propose to develop an entirely new class of hybrid material that contain regions of both zeolite and metal-organic framework (MOF) - we call these materials ZeoMOFs. Microporous materials, including zeolites and MOFs, make up one of the most important classes of material in current research: zeolites are heavily used in industry and MOFs are some of the most exciting materials to have been prepared over the last two decades. While their structural architectures look similar (both types of material are porous) their chemistries are quite different. This means that a material that was part zeolite and part MOF would undoubtedly have some very interesting properties. However, the synthesis of such an intimate ZeoMOF hybrid is difficult, and likely impossible, using traditional approaches because of the incompatibility of their synthesis conditions. This means we have to design a new approach. In this project we will develop some of the recent synthetic work we have completed in the area of manipulation of structures using the ADOR process. In this project we will use these recent developments to first prepare zeolite layers. Then under carefully controlled conditions where the zeolite layers remain stable we use use the 'softer' conditions used in MOF synthesis to intercalate MOF species in between the zeolite layers and connect them together. The initial materials prepared are likely to be disordered but as we gain the necessary experience with the chemistry we expect to prepare more crystalline porous solids. The materials will be challenging to characterise, and we will use a combination of scattering and magnetic resonance (and other) techniques to fully understand the structure of the materials and then we will complete an activity aimed at understanding the properties of the new solids, with particuar focus on ascertaining how the porosity, catalytic and adsorption (e.g. for separation) properties are modified compared to zeolites and MOFs.
