In this paper, we describe the preparation of Cu nanoparticles (NPs) loaded on a MIL-101 (Cr) metal-organic framework and its highly enhanced heterogeneous catalysis for reduction of aromatic nitro compounds. The obtained Cu/MIL-101 (Cr) nanocomposites were characterized by powder X-ray diffraction (PXRD), elemental analysis, scanning electron microscopy (SEM), transmission electron microscopy (TEM), inductively coupled plasma atomic emission spectroscopy (ICP-AES), and nitrogen adsorption-desorption isotherms at 77 K. The result reveals that both small Cu NPs with diameter of 2-3 nm and Cu NPs with average diameter of 100 nm are formed, and the small Cu NPs are embedded in MIL-101(Cr). The obtained Cu/MIL-101(Cr) nanocomposites showed highly enhanced catalytic activity for the reduction of aromatic nitro compounds. (C) 2013 Elsevier B.V. All rights reserved.
