Adsorption of Hydrazine Formed in a Radio-Frequency Discharge on Zeolites

Abstract

The adsorption of hydrazine formed in a nitrogen-hydrogen plasma prepared using radiofrequency discharge on sodium ion-exchanged zeolite (NaZ) or hydrogen ion-exchanged zeolite (HZ) was, studied. Although the adsorbed amount of hydrazine was two orders of magnitude less than that of ammonia, a hundred times larger amounts of hydrazine could be adsorbed on HZ than on NaZ (Table 1). Larger amounts of acidic sites on HZ would contribute to an increment of the amount of hydrazine adsorbed.
