Abstract
Perovskite-type oxides were successfully prepared using microwave-assisted process, and by XRD, XPS, BET, and $H_2-TPR$. Their catalytic activities for the combustion of benzene were also examined. Most of catalysts studied showed the perovskite crystalline phase with the particle size of 21~35 nm. The $LaMnO_3$ catalyst showed the highest activity and the conversion reached almost 100% at $250^{\circ}C$. The catalysts prepared by microwave-assisted process showed higher activity compared to those prepared sol-gel method. In addition, the catalytic activity was increased with an increase of calcination temperature of $LaMnO_3$-type catalyst. The TPR results on the measurement of redox property showed a good correlation with the order of catalytic activity on the benzene combustion reaction.
