実験手順
In 300 ml of pure water were dissolved 29 g of cobalt nitrate hexahydrate and 75 g of aluminum nitrate nonahydrate. A solution of 38.4 g of ammonium carbonate dissolved in 100 ml of pure water was gradually added thereto with stirring to form a gel-form precipitate. The precipitate was washed with pure water three times, dried at 100° C. overnight and calcined at 600° C. in an air stream. The calcined material was then calcined at 800° C. in a muffle furnace for 3 hours to a cobalt aluminate catalyst having a blue color.
