UiO-66类MOF的合成及其吸附应用

Synthesis of UiO-66-based MOFs and Their Adsorption Applications

作为金属有机骨架材料中代表性的一员,UiO-66及其衍生系列MOF不仅具有优异的稳定性,同时也保持了较大的比表面积和较优的水热稳定性及机械稳定性,近年来在环境污染治理领域尤其是水体净化方面表现出较好的发展潜力。介绍了UiO-66类MOF材料的几种主要合成方案,包括溶剂热法、机械研磨法、微波辅助合成以及电化学沉积。同时较为系统地总结了UiO-66类MOF材料作为吸附剂,针对二氧化碳气体的存储分离以及有机染料废水的净化处理等环境修复领域的发展现状。最后,基于此类MOF材料在吸附应用领域存在的问题和限制,对其未来发展所面临的困难和挑战提出了一些建议。

UiO-66 and its derivative series of MOFs,as a representative member of metal-organic framework materials,not only have excellent stability,but also have a large specific surface area and superior hydrothermal and mechanical stability,and have shown good development potential in the field of environmental pollution control,particularly in water purification,in recent years.The primary synthesis methods was presented for UiO-66-based MOF materials,including the solvothermal method,mechanical grinding method,microwave-assisted synthesis,and electrochemical deposition.The use of UiO-66-based MOF materials as adsorbents for environmental remediation tasks,such as capturing and separating carbon dioxide gas and purifying and treating organic dye effluents were also systematically summarized.Finally,some suggestions for the difficulties and challenges of their future development were made based on the problems and limitations of such materials in adsorption applications.
