项目摘要

In this project the student will develop new analytical technology to assess the quality of metal organic frameworks (MOFs). MOFs are hybrid microporous solids featuring high-surface areas and tuneable structures, which can be used in a diverse range of applications such as sensing, catalysis, drug delivery, and gas storage. Recent work looking at industrial methods for scalable production of MOFs has seen their production in flow reactors which allow scalable production with rapid synthesis and high space time yields. They do so "blind" however, with no immediate mechanism for characterising the product online, as all standard methods (XRD, BET, SEM etc) need time-consuming sample preparation and offline analysis. This is highly problematic as it precludes real-time quality assurance when producing materials, and optimisation of reaction conditions when starting production is slow and manually intensive. Here we wish to investigate a qualitatively distinct approach to monitoring MOF quality. As most key physical properties of MOFs are prohibitively difficult or impossible to analyse in-flow, this project will develop analysis technology that instead focuses on the end applications, developing and implementing online analysers that quantify how well the product will perform at a target application (e.g. catalysis, sensing, absorption etc), beginning with organic pollution remediation.

在这个项目中，学生将开发新的分析技术来评估金属有机框架（MOFs）的质量。MOFs是具有高表面积和可调结构的混合微孔固体，可用于各种应用，如传感，催化，药物输送和气体储存。最近的工作着眼于用于可规模化生产MOF的工业方法，已经看到它们在流动反应器中的生产，这允许具有快速合成和高时空产率的可规模化生产。然而，他们这样做是“盲目的”，没有立即在线表征产品的机制，因为所有标准方法（XRD，BET，SEM等）都需要耗时的样品制备和离线分析。这是非常有问题的，因为它排除了在生产材料时的实时质量保证，并且在开始生产时反应条件的优化是缓慢的和手动密集的。在这里，我们希望调查一个质量不同的方法来监测MOF质量。由于MOFs的大多数关键物理特性难以或不可能分析流入，该项目将开发分析技术，而不是专注于最终应用，开发和实施在线分析仪，量化产品在目标应用中的表现（例如催化，传感，吸收等），从有机污染修复开始。
