| Abstract: | With ceramic cordierite honeycomb as a carrier and Cu,Cu-NiO, Cu-NiO-La203 or Cu-NiO-Ce203 as active components, several catalysts were synthesized for the selective catalytic reduction of nitrogen oxide with urea as reductive agent. The activity of these catalysts was evaluated and compared in the range of 423 K and 623 K. The reasearch result indicates that the catalysts have high activity. |
