Abstract: Among the many alternatives to the classical Haber-Bosch method for fixing atmospheric nitrogen, plasma methods are often singled out as the most promising. This study demonstrates for the first time the possibility of fixing nitrogen with aqueous plasma at room temperature and atmospheric pressure – as well as without a catalyst and toxic chemicals – and obtaining two valuable products: nitroxyl (HNO) and hydroxylamine (NH2OH). A similar catalyst-free approach based on a reaction with a water dimer cation radical in aqueous plasma has also been demonstrated for the selective and controlled transformation of methane (CH4) into methanol (CH3OH) without overoxidation. Scaling up the process looks like a promising project, since the installation has no moving parts at all, and the entire process is carried out at atmospheric pressure. Thus, the installation does not need either special vacuum equipment or metal-intensive high-pressure reactors.
