Abstract—The effect of Ni cation supported on FAU(Y)
zeolite was prepared by aqueous solution ion exchange and
incipient wetness impregnation methods in the selective
catalytic reduction of nitric oxide using hydrogen as the
reactant in packed bed reactor. 0.5 and 3.5 wt% of Ni (II)
metals were loaded in the FAU(Y) zeolite. The samples were
characterized by X-ray diffraction, X-ray fluorescence and
scanning electron microscope. The obtained Ni/FAU has
enlarged pore size of octahedral shaped crystals with
approximately 0.22 ± 0.085 μm diameter. Ni loading did not
change the structure of FAU(Y) zeolite. Ni (II) loading with 3.5
wt% to FAU-Y zeolite by incipient wetness impregnation
method was shown higher nitric oxide conversion than aqueous
solution ion exchange method.
Index Terms—FAU (Y) zeolite, metal loading, nickel, nitric
oxide reduction.
