          摘要:

          金屬有機框架(MOFs)材料因具有比表面積大、孔隙率高及孔道易調、易功能化等特點而應用于各研究領域。然而,多數MOFs材料的化學穩定性和水熱穩定性較差,極大地限制其應用。鋯基MOFs材料UiO-66的骨架坍塌溫度高于500 ℃、可承受1.0 MPa的機械壓力并且具有超高穩定性從而引起了人們的關注。該文系統介紹了UiO-66制備方法的研究進展,其中干凝膠轉化法具有產品收率高、反應體積小及可連續生產等優點更具優勢;詳細介紹了有機配體、金屬節點和摻雜等改性方式對UiO-66結構的影響,結果表明對UiO-66結構進行改性可進一步提高其性能;總結了UiO-66在催化、氣體儲存和分離等方面的應用;最后,對UiO-66的未來發展方向進行了展望。

          Abstract:

          Metal-organic frameworks (MOFs) materials are widely used in various research fields due to their large specific surface area, high porosity, easy adjustment of pores and easy functionalization. However, the chemical stability and hydrothermal stability of most MOFs are poor, which greatly limits the application of MOFs. Zirconium-based MOFs material UiO-66 has attracted much attention due to its skeleton collapse temperature higher than 500 ℃, withstands 1.0 MPa mechanical pressure and has ultra-high stability. This paper systematically introduces the research progress of various synthesis methods of UiO-66, and it is believed that the dry gel conversion method has the advantages of high product yield, small reaction volume and continuous production. The effects of organic ligands, metal nodes and doping on the structure of UiO-66 were introduced in detail. The research results show that the modification of UiO-66 structure can further improve its performance. The application of UiO-66 in catalysis, gas storage and separation is summarized. The future development direction of UiO-66 is also prospected.
