| description | Copper and iron promoted ZrO<sub>2</sub> catalysts were prepared by one-pot synthesis using urea. The studied catalysts were characterized by XRD, N<sub>2</sub> physisorption, XPS, NH<sub>3</sub>-TPD, and tested in the selective catalytic reduction of NO with NH<sub>3</sub> (NH<sub>3</sub>-SCR) in the absence and presence of water vapor under the experimental conditions representative of exhaust gases from stationary sources. The influence of SO<sub>2</sub> on catalytic performance was also investigated. Among the studied catalysts, the Fe-Zr sample showed the most promising results in NH<sub>3</sub>-SCR, being active and highly selective to N<sub>2</sub>. The addition of SO<sub>2</sub> markedly improved NO and NH<sub>3</sub> conversions during NH<sub>3</sub>-SCR in the presence of H<sub>2</sub>O. The improvement in acidic surface properties is believed to be the cause. |
