Abstract

At a high space velocity of 120 000 mL g⁻¹ h⁻¹ and a relative humidity of 50–90%, 98% removal of 10 ppm NO has been achieved for over 237 h and no sign of deactivation was observed with mesostructured amorphous manganese oxides (AMO), due to the prevention of the catalyst active sites from deactivation.
