Facile fabrication of magnetically recyclable metal–organic framework nanocomposites for highly efficient and selective catalytic oxidation of benzylic C–H bonds

Abstract

HKUST-1@Fe₃O₄ chemically bonded core–shell nanoparticles have been prepared by growing HKUST-1 thin layers joined by carboxyl groups onto Fe₃O₄ nanospheres. These magnetic core–shell MOF nanostructures show exceptional catalytic activity for the oxidation of benzylic C–H bonds and they can be recovered by magnetic separation and reused without losing any activity.
