Ammonia synthesis using low-power consumption and eco-friendly methods has attracted increasing attention. Here, based on the Tesla turbine triboelectric nanogenerator (TENG), we designed a simple and effective self-powered ammonia synthesis system by N₂ discharge. Under the driving of the simulated waste gas, the Tesla turbine TENG showed high rotation speed and high output. In addition, the performance of two Tesla turbine TENGs with different gas path connections was systematically investigated and discussed. A controllable series-parallel connection with the control of gas supply time was also proposed. Taking advantage of the intrinsic high voltage, corona discharge in a N₂ atmosphere was simply realized by a Tesla turbine TENG. With the flow of N₂, the generated high-energy plasma can immediately react with water molecules to directly produce ammonia. The self-powered system achieved a yield of 2.14 μg h⁻¹ (0.126 μmol h⁻¹) under ambient conditions, showing great potential for large-scale synthesis.

使用低功耗和环保方法合成氨已引起越来越多的关注。在这里，我们基于特斯拉涡轮摩擦纳米发电机（TENG），设计了一种简单有效的 N ₂放电自供电氨合成系统。在模拟废气的驱动下，特斯拉涡轮TENG表现出高转速和高输出。此外，系统地研究和讨论了具有不同气路连接的两个特斯拉涡轮 TENG 的性能。还提出了一种可控制供气时间的可控串并联。利用固有的高电压，N ₂气氛中的电晕放电可以通过特斯拉涡轮机 TENG 轻松实现。随着N ₂的流动，产生的高能等离子体可以立即与水分子反应，直接产生氨。自供电系统在环境条件下的产量为2.14 μg h ^-1 (0.126 μmol h ^-1 )，显示出大规模合成的巨大潜力。
