“…OH and reactive oxygen species are important oxidizing species in plasma. In particular, OH has the best oxidation performance with an oxidation potential of 2.8 eV and O(1D) with an oxidation potential of 2.2 eV, which can oxidize and decompose a variety of CWAs [2,12].…”

“…Subsequently, researchers have conducted extensive research on plasma decontamination technology. Chen et al [12] used a pulsed power supply to excite a dielectric barrier electrode to decontaminate the mustard gas simulant 2-chloroethyl ethyl sulfide (2-CEES). At a discharge power of 45.2 W, the degradation rate of 180 ppm 2-CEES reached 93% after 20 min of plasma treatment.…”

Low-temperature plasma is a green and high efficiency technology for chemical warfare agents (CWAs) decontamination. However, traditional plasma devices suffer from the problems of high power composition and large power supply size, which limit their practical applications. In this paper, a self-driven microplasma decontamination system induced by dielectric-dielectric rotary triboelectric nanogenerator (dd-rTENG) was innovatively proposed for the decontamination of CWAs simulants. Microplasma was characterized by electrical measurements, optical emission spectrum and ozone concentration detection. With output voltage of -3460 V, the dd-rTENG can successfully excite microplasma in air. The reactive species such as OH, O(1D), Hα, and O3 were detected. The decontamination rate of 2-chloroethyl ethyl sulfide (2-CEES) reached 100 % within 3 min plasma treatment. While the decontamination rate of malathion and dimethyl methylphosphonate (DMMP) reached 65.92 % and 60.88 % after 7 min plasma treatment, respectively. In addition, the decontamination rates gradually decreased with the increasing of simulants concentration. The typical products were identified and analyzed. This study demonstrates the broad-spectrum and feasibility of the dd-rTENG-microplasma for CWAs elimination, which provides significant guidance for their practical applications in the future.
