Abstract
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.
