低温水系电化学合成氨研究进展

Research Progress in Low-temperature and Electrochemical Synthesis of Ammonia

氨的生产对工业发展和人类生活是至关重要的,目前仍以传统的Haber-Bosch工艺为主导,但反应条件苛刻,还会产生环境污染。电催化合成氨气是一种新型环保节能工艺,开发环境条件下合成氨电催化剂,具有重大经济价值和现实意义。综述了近年来低温水体系电化学合成氨领域的研究工作进展,讨论了以N_(2)和硝酸根水溶液为原料的电催化合成氨方法,并对电合成NH3的未来发展趋势进行了预测。

Ammonia production is very important for industrial development and human life.At present,it is still dominated by the traditional Haber-Bosch process,but the reaction conditions are harsh and environmental pollution will be produced.Electrocatalytic synthesis of ammonia gas is a new technology of environmental protection and energy saving.It is of great economic value and practical significance to develop electrocatalyst for synthesis of ammonia under environmental conditions.In this paper,the research progress in the field of electrochemical synthesis of ammonia in low temperature water system in recent years was reviewed.The electrocatalytic synthesis of ammonia from N_(2)and nitrate aqueous solution was discussed,and the future development trend of electrosynthesis of NH3 was described.
