Synergistic degradation of fluorene in soil by dielectric barrier discharge plasma combined with P25/NH2-MIL-125(Ti)

Degradation of organic pollutants combining plasma discharges generated within soil with TiO2 and ZnO catalysts: Comparative analysis, optimization and mechanisms

“…Additionally, O 3 can be decomposed on the catalyst surface resulting in the generation of atomic oxygen (reaction (22). Furthermore, additional superoxide anions can be generated through the reaction of e cb − and molecular oxygen (23) and the highly reactive OH radical resulting from h vb + reacting with water present in the soil (reaction (24) [69]:…”

“…More recently, the addition of TiO 2 , as well as CeO 2 catalysts to a DBD system significantly improved the degradation of pyrene by 15-16% in both cases, highlighting the obvious synergistic effect with plasma [23]. In addition, the combination of a Ti-based metal organic framework catalyst with a DBD reactor resulted in increased degradation efficiency of fluorene in soil under relatively low applied voltage [24]. Apart from photocatalysts, the presence of Fe 0 was reported to accelerate the decomposition of chloramphenicol in DBD systems [25].…”

Remediation of water contaminated with polycyclic aromatic hydrocarbons using liquid phase plasma: Influence of electrical discharge condition

“…As active species are fundamentally generated through electron impact dissociation (Mai-Prochnow et al, 2021), the determination of the electron temperature is important for understanding and optimizing LPP. However, there is hardly any specific plasma state in numerous studies on degradation of organic pollutants using plasma technology comparing degradation efficiency varying electrical discharge conditions (Li et al, 2016;Zhan et al, 2018;Lu et al, 2022). Therefore, we calculated electron temperature and compared it to electrical discharge conditions; active species as shown in Figures 6A, B.…”
