Self-powered ammonia synthesis under ambient conditions via N2 discharge driven by Tesla turbine triboelectric nanogenerators

Abstract

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.

New framework of integrated electrocatalysis systems for nitrogen fixation

“…However, during the investigation, we found several limitations restricting the development of the TENG-based nitrogen fixation system. First, the confined application range keeps most of the studies at the experimental level; although some researchers have tried to integrate experimental results with theoretical assumptions 96 to further optimize their works, the conversion efficiency cannot be fully verified. The second issue is the unpredictability of mechanical energy sources, which makes it more imperative and indispensable to enhance the energy harvesting efficiency of TENG devices.…”
