Abstract

CeO₂/TiO₂ catalysts were fabricated by dry ball milling in the presence or absence of an organic ligand. It was found that the catalysts prepared by ligand-assisted ball milling exhibited high NH₃-SCR activities due to the interaction between cerium ions and ligand molecules resulting in good dispersion, a high Ce³⁺ ratio and high reducibility of cerium species.
