A dielectric barrier discharge plasma reactor coupled to an infrared red (DRIFT) cell has been developed and implemented in the laboratory following a collaborative work [1]. The first successful results were obtained from the real time observation of 4 volatile organic compounds (VOCs) decomposition (isopropanol: IPA, acetone, ethanol and toluene) on 3 metal oxide surfaces (g-Al2O3, TiO2, CeO2). Here, we present the results of the plasma treatment of IPA on g-Al2O3, which led to its oxidation in acetone. Upon prolonged plasma treatment time, acetone decomposed into carboxylic acids. On TiO2 and CeO2 surface, it led to the formation of acetic and/or formic acids. Ozone and CO2 were also observed on ceria surface

These preliminary studies highlight the originality of this new system regarding in-situ surface characterization during non thermal plasma treatment.
