In this research, M/Cs1.5H1.5PW/Al2O3 (M = Ni or/and Mo) nanocatalysts were
prepared via 2 steps with the impregnation method and the effect of molybdenum on
the characteristic and catalytic properties of the prepared samples was studied. The
synthesized samples were characterized by X-ray diffraction (XRD), temperature
programmed reduction, temperature programmed desorption (TPD), and energy
dispersive X-ray spectroscopy techniques. Morphology of the samples was studied
by field emission scanning electron microscope (FESEM) and surface area, pore
volume and pore size of the compounds were measured by BET method. In the
XRD patterns of the prepared catalysts, the H3PW12O40 phase was observed. The
FESEM images showed that the synthesized particles were in nanoscale. The results
of TPD studies indicated that the total acid site of Ni–Mo/Cs1.5H1.5PW/Al2O3
catalyst was more than the others. The catalytic activity of the nanocatalysts in
hydrocracking of n-decane indicated that Ni–Mo/Cs1.5H1.5PW/Al2O3 nanocatalyst
had the highest catalytic activity.
