Abstract: Ammonia is one of the most important chemical raw materials for human production and life. However, the traditional ammonia synthesis process needs to be performed under high temperature and high pressure conditions, and its average annual energy consumption accounts for about 1~2% of the world's total energy consumption. At the same time, due to the burning of fossil fuels, this process inevitably increases the greenhouse gas emission. Therefore, finding suitable green alternative methods for ammonia synthesis with high efficiency, low energy consumption, and less greenhouse gas emission under mild condition has become a hot topic for ammonia synthesis. Plasma technology for ammonia synthesis has received increasing attention. This article reviews the recent achievements on plasma synthesis of ammonia at home and abroad, including the plasma sources, catalysts, reactor structures, discharge parameters, reaction mechanisms, etc. In addition, based on the current research status in this field, the development direction of plasma assisted ammonia synthesis is prospected.
