Abstract Catalysts High surface area, e.g. precipitated, ammonia catalyst precursors are promoted with an alkali metal salt of a transition metal acid, e.g. potassium ferrate, ferrite, permanganate, ruthenate, chromate, or ferrocyanide. The use of such promoters in place of potassium carbonate enables the catalyst to be activated at lower temperatures thus reducing the risk of sintering of the active metal.
