Abstract:

UiO-66 is a typical Zr-based metal-organic framework with large surface area, high porosity, and adjustable micro-pore size and is easily functionalized. Unlike most MOFs, UiO-66 exhibits excellent chemical stability, mechanical stability, thermal stability and water resistance, indicating great application prospect in the fields of adsorption and catalysis. In this paper, the synthesis methods of UiO-66 were introduced in detail, including solvothermal, mechanochemical, microwave-assisted, continuous flow and dry-gel conversion methods. The dry-gel conversion method has the advantages of high yield, simple purification & activation process and no organic waste production, showing great potential in commercialization. Progress on modified UiO-66 materials in the field of adsorption of toxic industrial chemicals and catalytic degradation of chemical warfare agents has been reviewed, and an outlook on the development trend of electrospun nanofiber supported UiO-66 in the field of chemical protection was made.

Key words: porous media, UiO-66, adsorption, catalysis, toxic industrial chemicals, chemical warfare agents

摘要:

UiO-66除了具备其他MOFs材料的比表面积大、孔隙率高及孔道易调、易功能化等特点外,与大多数MOFs 材料不同,还具有优异的化学稳定性、机械稳定性、热稳定性和抗水性能,使其在吸附及催化领域具有巨大的应用前景。本文详细介绍了UiO-66的合成方法最新研究进展,包括溶剂热法、机械研磨法、微波辅助法、持续流法及干胶转化法,同时指出干胶转化法产品收率高,纯化、活化过程简单且不产生有机废液,是UiO-66合成及未来工业化生产的发展方向。同时综述了改性UiO-66材料近年来在有毒工业化学品吸附及化学战剂催化降解领域中的研究进展,展望了静电纺纳米纤维负载UiO-66在化学防护领域应用的发展趋势。
