“…Limited additional results on direct N 2 to nitrate electrooxidation have been reported, but are based on noble-metal electrocatalysts. A theoretical study 107 indicates a noble metal, such as IrO 2 (110), as an excellent catalyst because it limits the side oxygen evolution reaction. Avoiding this side reaction is undoubtedly a challenge.…”

“…Exciting developments have been recently proposed in producing fertilisers from the air by non-thermal plasma. However, they are limited to nitrate production, [108][109][110] while producing ammonia by nonthermal plasma is harder. Still, plasma-activated electrochemical ammonia synthesis from nitrogen and water has been reported.…”

“…The application of plasma‐treated water to potato leaves during the period of vegetative growth of potatoes provides an increase in tuber yield (Rashid et al, 2022). Activation of seed germination of pea, corn, rice and other crops is possible due to their wettability with plasma‐activated water (Rathore et al, 2022; Skarpa et al, 2020; Sze et al, 2021). For the widespread introduction of the plasma method of irrigation water treatment in agriculture, these individual laboratory experiments are clearly insufficient.…”

Cold atmospheric plasma technology activates water, but the effect of plasma‐activated wastewater on vegetables remains unexplored. The first garden bed was irrigated with wastewater from the Zhulebinsky collector after ultraviolet treatment, and the second bed was irrigated after plasma activation. The third garden bed was irrigated with plasma‐activated wastewater from the Kuryanovsky channel. The bacterial concentration in the water for all experiments was 106 CFU mL−1, the nitrate content in the water for the first garden bed was 6.3 mg L−1, and for the second and third garden beds, it was 10 mg L−1. The average fresh weight of radish roots from the garden bed when irrigated with plasma‐activated water from the Zhulebinsky collector was 7% higher than that when irrigated with ultraviolet‐treated water. The increase in the average fresh weight of stems with leaves was 13%. The highest total and average fresh weights of radish were observed in the garden bed when irrigated with plasma‐activated water from the Kuryanovsky channel. Compared with water irrigation from the Zhulebinsky collector, the increase in average fresh weight was 16%, and compared with irrigation with ultraviolet‐treated water, it was 29%. Reuse of plasma‐activated wastewater increases the yield of vegetables during irrigation and contributes to the saving of fresh water resources.

“…The fixation process applies plasma at the surface of air and water to form soluble reactive oxygen and nitrogen species (RONS). The species include nitrate (NO − 3 ) and other forms of nitrogen compounds, which can all be used as fertilizers [5,7]. Plasma-assisted nitrogen fixation works under atmospheric conditions without emission of green house gases.…”

Plasma-assisted nitrogen fixation at atmospheric pressure is a clean and decentralized method for fertilizer production. Among many different plasma discharge types, dielectric barrier discharge (DBD) is one of the few that can generate high output of nitrogen compounds at atmospheric conditions for fertilizer usage. Most DBD generators operate at kHz switching frequencies, however, previous research has found that discharge activities occur at the intervals of the greatest voltage slew rate. The finding implies that operating at higher frequencies can lead to more discharge activities and higher plasma generation. This paper presents a MHz Class E power amplifier with frequency selection to generate DBD plasma at two distinct frequencies. The power amplifier achieves a peak efficiency of 91.5% and outputs 600 W at frequencies of 12.4 MHz and 15.5 MHz.
