Ligand-assisted mechanochemical synthesis of ceria-based catalysts for the selective catalytic reduction of NO by NH3

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 disper...

More Information
Summary: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.
