摘要: Abstract The turnover number for ammonia synthesis was found to be smaller on very small iron particles than larger ones, but it could enhanced by a pretreatment which seemed bring about surface reconstruction induced nitrogen. same decreases the uptake of carbon monoxide catalyst and also anisotropy energy barrier relaxation metallic magnetization, as determined Mossbauer spectroscopy. These new results can explained creation upon catalyst, C7 atoms particles, where Ci atom is one with i nearest neighbors. As concentration expected nitrogen reconstruction, concluded that are more active others in synthesis.
