ABSTRACT:
An iron oxide containing precursor to a catalyst, for e.g. ammonia synthesis having a surface area above 10 m.sup.2.g.sup.-1 also containing alumina and cobalt oxide. The latter serves to increase the catalytic activity and/or reduce the rate of decline of catalytic activity. For use as an ammonia synthesis catalyst precursor, an alkali metal, e.g. potassium, is preferably incorporated into the composition to promote catalytic activity. The composition may be made by precipitation followed by calcination.
