摘要:

利用水热法一步合成了金属有机骨架(MOFs)材料UiO-67-Sal, 并将3种铜盐固定在其表面, 研究了3种铜MOFs材料催化芳香醇选择性氧化的性能. 结果表明, UiO-67-Sal-CuCl2催化剂对芳香醇选择性氧化反应具有良好的催化活性, 且在重复使用4次后, 依然保持较好的催化效果.

Abstract:

Metal-organic-frameworks(MOFs) are a class of hybrid materials with unique porous structure. MOFs possess open pores of a permanent crystalline matrix, made of organic ligands and metal ions or clusters via coordination interactions. Permanently microporous MOFs materials have attracted considerable attention due to the large internal surface areas, uniform channels, thermal stability and other potential applications, such as gas separation and storage, catalysis, drug release and chemical sensing. The Zr-based MOF material(UiO-67-Sal) was functionalized through one-step hydrothermal synthesis, and the three copper(Ⅱ) salts were immobilized onto the UiO-67-salen. The three resulting Cu(Ⅱ)-UiO-67-Sal MOFs were evaluated for aerobic selective oxidation of a range of primary aromatic alcohols. The UiO-66-Sal-CuCl2 catalyst exhibited excellent activity toward the selective erobic oxidation of primary aromatic alcohols using oxygen molecular as the oxygen source. Furthermore, the UiO-66-Sal-CuCl2 catalyst showed a good recycle performance.
