本文从N_2分子和H_2分子的前沿轨道对称性入手,通过分析N_2分子的结构,络台性能,探讨N_2和H_2反应的机理,指出了N_2和H_2合成氨反应的困难所在,提出合成氨生产上应继续寻找最合适的活化N_2分子的催化剂,同时不应忽视H_2的活化。

In this paper, the frontier orbital symmetry of N_2 molecules and H_2 molecules are discussed. The mechanism of reaction of N_2 and H_2 is discussed by analyzing the structure and network performance of N_2 molecules. The difficulties of ammonia reaction between N_2 and H_2 are pointed out. It is suggested that the production of ammonia should continue Look for the most suitable activator of activated N 2 molecules, while not neglecting the activation of H 2.
