Low-Temperature Selective Catalytic Reduction of NO _x with NH₃ over Mn-Ce Composites Synthesized by Polymer-Assisted Deposition.

ABSTRACT: The Mn _x Ce _y binary catalysts with a three-dimensional network structure were successfully prepared via a polymer-assisted deposition method using ethylenediaminetetraacetic acid and polyethyleneimine as complexing agents. The developed pore structure could facilitate the gas diffusion and accelerate the catalytic reaction for NH₃ selective catalytic reduction (SCR). Moreover, the addition of Ce is beneficial for the exposure of active sites on the catalyst surface and increases the adsorption of the NH₃ and NO species. Therefore, the Mn₁Ce₁ catalyst exhibits the best catalytic activity for NO _x removal with a conversion rate of 97% at 180 °C, superior water resistance, and favorable stabilit
