摘要：

Recent theoretical models for the kinetics of ammonia synthesis,- based on the mechanism derived from UHV-studies with single crystals and using data on the adsorptive properties of nitrogen on potasium covered Fe(111) surfaces as essential input parameters-, were found to successfully describe the rate with industrial catalysts. Using thermal desorption spectroscopy, it is demonstrated that the K-Fe(111) model systems and industrial ammonia synthesis catalysts exhibit indeed very similar properties with respect to nitrogen adsorption which result is considered as direct confirmation for the assumptions underlying the theoretical treatment.
