Synthesis of NiMo/Al2O3 hydrodesulphurization nanocatalyst by one pot co-impregnation route

Abstract

Nano NiMo/γ-Al2O3 catalysts was prepared by using the impregnation method of nickel chloride (as a source of nickel) and ammonium molybdate (as a source of molybdenum) on the alumina. Then, they were characterized and studied by many techniques, including X-ray diffraction (XRD), Fourier transform infrared (FTIR), field emission scanning electron microscope (FESEM) and thermo-gravimetric analysis (TGA. From X-ray diffraction (XRD) spectrometry, results showed that the particle size was (11.903 nm) for the prepared nano NiMo/γ-Al2O3 catalyst and that the nickel and molybdenum atoms were incorporated into the mesoporous alumina channels. Finally, the shape of the particle is spherical or nearly spherical as seen in FESEM image.
