It is noteworthy that the work combined plasma discharge with electroreduction processes, resulting in the sustainable synthesis of NH₂OH from ambient air and H₂O. The proposed mechanism not only mitigates the energy consumption problem during NH₂OH electrosynthesis but also reduces the emission of NO_x. Furthermore, it provides an important scientific reference for the renewable electrosynthesis of NH₂OH and other nitrogen-containing compounds. Nevertheless, the large-scale synthesis of HNO₃ plasma continues to present significant challenges, including high energy consumption and low air conversion efficiency. In particular, the key to industrialisation is the further realisation of high-concentration HNO₃, the advancement of the scale-up and low-cost preparation of catalytic electrodes, and the rational construction of the reactive electrostack.
