摘要
The ammonia decomposition over iron in the presence of water vapor has been studied. Water vapor retards this process, though no change of the apparent activation energy is observed. Despite noticeable influence of the water vapor on the rate of ammonia decomposition the sticking coefficient of ammonia on iron is not affected. Those observations were explained by the retardation of nitrogen molecules recombination on the iron surface due to the presence of oxygen atoms. The positive influence of water vapor on the rate of iron nitriding is also elucidated.
