| 摘要: 用冶金法、还原扩散法、共沉淀法制得了LaNiFe,并对其催化合成氨反应性能进行了研究。实验结果表明:还原扩散法,共沉淀法制得的LaNi4Fe催化活性均比冶金法好。X—射线分析指出LaNi4Fe在合成氨反应过程中变为Ni4Fe和LaN。 |

| Abstract: The title compound has been prepared by use of metallurgy, reduction-diffusion and coprecipitation methods. It has catalytic activity for synthesis of ammonia. Experimental results show that the catalytic activity of LaNi4Fe made by coprecipitation or reduction-diffusion is better than that of LaNi4Fe made by metallurgy.X-ray diffusion diffraction pattern shows that LaNi4Fe convert into Ni4Fe and LaN in the process of synthesis of ammonia. |
| Keywords: reduction-diffusion coprecipitation catalytic activity of LaNi4Fe synthesis of ammonia |
