Carbon nanotubes (CNTs) supported manganese oxide catalysts were prepared through different thermal treatment routes and used for low-temperature selective catalytic reduction of NO with NH3. The MnOx/CNTs catalyst prepared by calcined the precursor in air at 300 degrees C showed lower NO conversions than that treated at 250 degrees C, while it showed higher NO conversions than the one calcined in nitrogen. BET, TGA, XRD and H-2-TPR results indicated that CNTs may impose effects on the oxidation state and redox ability of the manganese oxide and hence on the catalytic activity during the calcination process at given temperatures.
