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.
