摘要
A Zr-based metal-organic framework with bipyridine units (UiO-67) has been utilized for the immobilization of catalytically active iron species via a post-synthetic metalation method. UiO-67 bipyridine MOF was synthesized through a simple solvothermal method and was shown to have a UiO-type structure. Post-synthetic metalation of UiO-67 MOF was performed for the immobilization of the catalytically active FeCl3. FT-IR and EDX element map suggested that FeCl3 is coordinately bonded to the UiO-67 bipyridine framework. The synthesized UiO67-FeCl3 catalyst was used for the aerobic oxidation of alcohols and benzylic compounds in the presence of molecular oxygen. In addition, the UiO-67-FeCl3 catalyst can be reused as a solid heterogeneous catalyst without compromising its activity and selectivity.
