A total oxidation of p-xylene by non-thermal plasma reactor (NTP) using anodized aluminium oxide (AAO) support. The AAO is promoted with Mn and Co oxides by impregnation method. The formation of Mn and Co oxides on AAO is confirmed using XRD, XPS and FE-SEM. The performances of the NTP reactor are tested by varying applied voltages and the specific input energies. The observed major and by-products by the decomposition of p-xylene are carbon oxides (CO and CO2) and alcohol, aldehydes respectively. Our experimental results suggested that the Mn, Co oxides on AAO are improved the conversion efficiency, high selectivity than bare AAO. Especially, MnOx shows better performance than CoOx, due to the formation of atomic oxygen by in-situ decomposition of ozone. Overall, the MnOx and CoOx on AAO are efficient catalysts to decompose the toxic p-xylene by NTP technique |
