Plasma assisted green ammonia production from water and nitrogen at atmospheric pressure

Increasing fossil-free global energy demands have motivated the scientific community to investigate new clean and sustainable techniques that can meet global energy demands. The production of green and sustainable fuel, such as ammonia (NH₃), from base molecules like water and nitrogen using electricity from renewable sources shows great potential to solve energy issues. Non-thermal plasma-based NH₃ synthesis has great potential for carbon-free fertilizer production powered by renewable electricity. We developed a non-thermal plasma couple with a catalyst for a higher ammonia production rate. The studied plasma technique offers ~0.84 % NH₃ concentration with ~95 % selectivity and a 120 µmol/s production rate by integrating a catalytic reduction system with plasma. Compared with previous studies on NH₃ synthesis from N₂, the remarkable NH₃ yield (300–400-fold higher). These promising results provide a breakthrough in the transition toward sustainable and environmentally friendly NH₃ production.
