“…A different strategy is to produce liquid fertilizers, where water can be used in a gliding arc reactor and the nitrogen is fixed as NO2 − and NO3 − . This configuration was developed by Mizukoshi et al [72], where a stable plasma was generated in this system. Another type of warm plasma, the so-named transient spark discharge, was used by Janda et al [73] for NOx production.…”

Recent Progress of Plasma-Assisted Nitrogen Fixation Research: A Review

et al. 2018

Nitrogen is an essential element to plants, animals, human beings and all the other living things on earth. Nitrogen fixation, which converts inert atmospheric nitrogen into ammonia or other valuable substances, is a very important part of the nitrogen cycle. The Haber-Bosch process plays the dominant role in the chemical nitrogen fixation as it produces a large amount of ammonia to meet the demand from the agriculture and chemical industries. However, due to the high energy consumption and related environmental concerns, increasing attention is being given to alternative (greener) nitrogen fixation processes. Among different approaches, plasma-assisted nitrogen fixation is one of the most promising methods since it has many advantages over others. These include operating at mild operation conditions, a green environmental profile and suitability for decentralized production. This review covers the research progress in the field of plasma-assisted nitrogen fixation achieved in the past five years. Both the production of NOx and the synthesis of ammonia are included, and discussion on plasma reactors, operation parameters and plasma-catalysts are given. In addition, outlooks and suggestions for future research are also given.

Effective Dissolution of Biomass in Ionic Liquids by Irradiation of Non-Thermal Atmospheric Pressure Plasma

et al. 2017

Biomass was dissolved in ionic liquids under non-thermal atmospheric pressure plasma irradiation. On plasma irradiation, the amount of dissolved biomass in the ionic liquids increased from 15 to 29 mg for bagasse and from 26 to 36 mg for Japanese cedar. The high solubility is attributed to the deconstruction of the lignin network by active chemical species generated by the plasma. Selective extraction of cellulose from biomass was observed under the plasma irradiation.

“…The main peaks detected in the spectrum were OH (309 nm), Hα (656 nm), Hβ (486 nm), O (777 nm), and He (589 nm). 21,22 The strong OH band indicates that OH radical was generated in the gas phase. Since the OH band was dominant in the spectrum, this plasma is expected to be suitable for the degradation of salicylic acid.…”
