Volatile Organic Compounds (VOCs), particularly the chlorine containing organic compounds, are regarded as the most dangerous pollutants due to qualities such as toxicity, carcinogenicity, diffusivity, and volatility, which have a negative impact on human health and the environment. Abatement of Cl group containing VOCs to less hazardous and industrially usable compounds is a unique way to reducing VOC related concerns. Non Thermal Plasma (NTP) assisted catalysis is the ideal technology for the efficient abatement of Cl VOCs because it is more selective, energy efficient, and requires no solvent at relatively mild circumstances than other degrading methods. For this work, we chose three distinct chloro-containing gaseous pollutants, such as chlorobenzene, O-Dichlorobenzene, and dichloromethane, to assess their efficiency and mechanism with respect to catalyst by a coaxial DBD reactor. Degraded products are discovered and evaluated using GC, GCMS, FTIR, and OES. Gaussian 16 W software's computational work assisted in determining the most viable degradation pathway from among various options. Dichloromethane is more efficient than other VOCs such as chlorobenzene and o-dichlorobenzene, both with and without catalyst. MnO2 and CeO2 catalysts are utilized for the above VOCs, and MnO2 has higher efficiency than CeO2 (analyzed using XRD and FESEM graphs), resulting in increased degradation efficiency for the above compounds. The deposited products are oxidized in the plasma reactor, and with catalytic assistance, many harmful helpful compounds are generated, while harmful products are transformed into CO2, CO, H2O, and other useful hydrocarbons. Finally, a look at future problems and scope in the development of NTP-assisted VOC catalytic.
