摘要:

氮气是储量丰富且廉价易得的氮源,但无法被人类或动植物直接吸收利用,只有通过化学或生物方法将空气中游离的氮气转化为含氮化合物才能被人类应用于食品或其他工业生产中,因此氮气的固定及转化已经逐渐成为新的研究热点。而氨是一种非常重要的无机化工产品,其在农业、医药、储能等行业中有着重要的作用,且需求量随着社会日益发展和人口的不断增加而不断增加。首先简单介绍了现有的氮气固定合成氨方法及其作用机理,随后重点综述了氮气电化学合成氨催化剂的研究现状,最后对氮气电化学合成氨催化剂的未来发展趋势进行了展望。

Abstract:

Nitrogen (N2) is an important component of atmosphere, so human, animal or plant cannot used or absorbed it directly, and then it is necessary of converting N2 to nitrogen-containing compounds that can be used in human food and other industrial production. Therefore, the fixation and conversion of nitrogen has gradually become a new research hotspot. Ammonia is a very important inorganic chemical product, which plays an important role in agriculture, medicine, energy storage and other industries, and the demand is increasing with the development of society and the increasing population. The existing nitrogen-fixed ammonia synthesis method and its mechanism are briefly introduced. Then the research status of nitrogen electrochemical synthesis ammonia catalyst is reviewed. Finally, the future development trend of nitrogen electrochemical synthesis ammonia catalyst is prospected.

Key words: electrochemistry, nitrogen reduction, synthesis of ammonia, reaction mechanisms, catalyst, catalysis
