A γ-FeO-modified nanoflower-MnO/attapulgite catalyst for low temperature SCR of NO with NH
A mesoporous γ-Fe 2 O 3 -modified nanoflower-MnO 2 /attapulgite (γ-Fe 2 O 3 /nf-MnO 2 -ATP) catalyst was fabricated through a facile hydrothermal method. The results of TEM and XRD indicated that γ-Fe 2 O 3 /nf-MnO 2 -ATP presented a beautiful nanoflower shape and good dispersion. The BET results sh...
