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

FeMnTiOx 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 degrees C, more than 80% N-2 selectivity at 75-200 degrees C, and excellent H2O durability for the selective catalytic reduction of NO by NH3 with a space velocity of 30000 mL g(-1) h(-1).
