Novel Preparation of Cu and Fe Zirconia Supported Catalysts for Selective Catalytic Reduction of NO with NH3
Abstract : Copper and iron promoted ZrO2 catalysts were prepared by one-pot synthesis using urea.
The studied catalysts were characterized by XRD, N2 physisorption, XPS, NH3-TPD, and tested in
the selective catalytic reduction of NO with NH3 (NH3-SCR) in the absence and presence of water
vapor under the experimental conditions representative of exhaust gases from stationary sources.
The influence of SO2 on catalytic performance was also investigated. Among the studied catalysts,
the Fe-Zr sample showed the most promising results in NH3-SCR, being active and highly selective
to N2. The addition of SO2 markedly improved NO and NH3 conversions during NH3-SCR in the
presence of H2O. The improvement in acidic surface properties is believed to be the cause.
