Abstract Catalysts An iron oxide containing precursor to a catalyst, for eg ammonia synthesis having a surface area above 10 m2.g-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, eg potassium, is preferably incorpor- ated into the composition to promote catalytic activity. The composition may be made by precipitation followed by calcination.
