Dielectric barrier discharge plasma-assisted catalytic reduction of NOx over Mn-Cu catalyst

Manganese-copper bimetal oxide catalysts supported on ZSM5 were produced by incipient wetness impregnation for selective catalytic reduction of NO with dielectric barrier discharge plasma. The significant enhanced activity of catalysts was exhibited with the increasing calcination temperature from 350 degrees C to 550 degrees C, especially in the higher discharge power. NO removal efficiency reached 95% with the manganese-copper bimetal oxide catalyst of 550 degrees C at 18W. The catalysts samples were characterized by XRD and BET. This results show that the CuMn/ZSM-5 catalyst possesses more NO reduction activity with the adding calcination temperature.
