Hybridized nanocatalysts (AgNPs-Fe2O3) were prepared with silver nitrate and ferric chloride in the presence of sodium borohydride. The synthesized nanocatalyst was calcined, milled, sieved for further applications. characterized using Fourier transform infrared spectroscopy (FTIR) identification functional moieties involved synthesis nanocatalyst. vibrations Fe Ag found at 566, 790 892 cm-1. crystalline nature determined X-ray diffraction (XRD) studies. peaks can be seen 2θ values 30.42, 44.36, 62.45, 42.24 53.25. morphology elemental analysis studied scanning electron microscopy (SEM) energy dispersive (EDAX). particles are to spherical shape. signal 3.0 keV 0.7, 6.3, 7.0 keV, respectively. employed remediation 2,4-dinitrophenol. AgNPs-Fe2O3 completely reduced (97%) 2,4-dinitrophenol 2,4-diaminophenol within 24 h.
