The surface structure and atomic composition of triply promoted (KzO/A120,/Ca0) fused iron catalysts, used in the industrial synthesis of ammonia, have been examined by temperature-programmed desorption (i) after having been reduced in hydrogen and (ii) after having synthesised ammonia from a hydrog
