Promoter effects of alkali metal nitrates and alkali earth metal nitrates on Ru/AC (active carbon) were studied in order to prepare an effective catalyst for ammonia synthesis. Of alkali metal nitrates, RbNO 3 was more effective than C s NO 3 and KNO 3. Alkali earth metal (Mg, Ca, Sr, Ba) nitrates were also found to be effective promoters on Ru/AC catalysts. Of them heavier alkali earth metal elements were more effective (Ba> Sr> Ca> Mg). Ba (NO 3) 2 was as effective as CSNO 3, which was not expected from the stand point of …
