MnO2 doped CeO2 with tailored 3-D channels exhibits excellent performance for NH3-SCR of NO

Abstract

Diffusion behaviour during NO conversion by selective catalytic reduction by NH₃ (NH₃-SCR) was simulated by a molecular dynamics method. MnCeO_x with tailored 3-D channels was obtained from a KIT-6 template. The remarkable performance of the NH₃-SCR results from a large surface area for chemisorption and appropriately sized channels for mass diffusion.
