Abstract
Iron molybdate Fe2(MoO4)3 nanoparticles were prepared via heating an oxalate precursor in air at 500°C. The precursor was characterized by Fourier transform infrared (FTIR) spectroscopy, and its thermal behavior was studied by thermal gravimetric analysis (TGA) and differential thermal analysis (DTA). The as-prepared iron molybdate was characterized by X-ray diffraction (XRD), transmission electron microscopy (TEM), and the Brunauer–Emmett–Teller technique (BET), and its catalytic performance was tested. Fe2(MoO4)3 exhibits a very high efficiency in the catalytic reduction of the nitro group to the amine group in the ortho-, meta-, and paranitrophenol isomers. The reduction was monitored using UV visible absorption measurements.
