Ag-based magnetic metal organic framework nanocomposite as catalyst for nitrophenol removal

In this work a silver based Magnetic Metal Organic Framework Nanocomposite (MMOFC) was prepared in which nanoparticles of magnetic iron oxide and nano Ag MOF of Ag-Benzene tricarboxylic acid form a nanostructure (IO@Ag-BTC). The synthesized nanostructure was characterized using XRD, SEM, EDS, TEM, TGA, IR and Raman spectroscopic techniques. The optical and morphological characterization confirmed the formation of a large number of low-symmetry spherical shaped particles of size ~53 nm together with some rod-like shapes with aspect ratio ranging from 3.7 to 11.23. The potential of the synthesized IO@Ag-BTC MMOFCs towards the reduction of 4-nitrophenol (4-NP) to 4-aminophenol (4-AP) was demonstrated.
