Improved low temperature NH3-SCR performance of FeMnTiOx mixed oxide with CTAB-assisted synthesis

Abstract

FeMnTiO_x mixed oxide is prepared by the CTAB-assisted co-precipitation method, and the transformation of anatase into rutile is inhibited by CTAB to some extent. The catalyst obtained in the present work shows nearly 100% NO conversion at 100–350 °C, more than 80% N₂ selectivity at 75–200 °C, and excellent H₂O durability for the selective catalytic reduction of NO by NH₃ with a space velocity of 30 000 mL g⁻¹ h⁻¹.
