| Abstract: | "A series of Fe doped LaMnO(3) catalysts were prepared to control the production of byproducts such as O(3), N(2)O, and CO, during the degradation of volatile organic compounds with a non-thermal plasma. Eliminating these potentially toxic byproducts will make non-thermal plasma technologies applicable for a wider range of commercial applications. The modified LaMnO(3) catalysts are combined in NTP-catalysis reactor with optimal configuration. Experimental results show that doping Fe on LaMnO(3) catalysts can not only enhance the oxidation of o-xylene, but also lower the emission levels of byproducts. LaMn(0.9)Fe(0.1)O(3) catalyst shows the best catalytic activity among the formulations tested herein. In addition to the strong mineralization of 88.1 %, the catalyst has the highest performance for o-xylene conversion (91.3 %), O(3) inhibition efficiency (84.9 %), and N(2)O inhibition efficiency (61.2 %) due to the strong concentration of active oxygen species on the surface of the catalyst. Moreover, the high reducibility of Fe(3+) demonstrated with H(2)-TPR (hydrogen temperature-programed reduction) further enhances the removal of O(3) by oxygen species exchange between Mn(3+)/Mn(4+) and Fe(2+)/Fe(3+)" |
