A series of sodium-exchanged Y-zeolites with different Si/Al ratios have been prepared from the proton and ammonium ion forms of Y-zeolite(faujasite) by means of a solution ion exchange. The prepared catalysts have been characterized by the various analytical techniques and the NOx conversion rates of the catalysts were measured with non-thermal plasma assisted catalytic system. Specific surface areas measured by the BET increased in the order of the NaY series 708, 712, 100, 720, 760. The results of the elemental analyses showed that the Si/Al ratio of the catalysts increased gradually in the order of NaY 100, NaY 712, NaY 720, NaY 760, NaY 780.
