TL;DR: Performing synthesis at high temperatures ensures that only the most stable binding sites are occupied, yielding a sinter-resistant, atomically dispersed catalyst.
Journal ArticleDOI
MnOx-CeO2 mixed oxides prepared by co-precipitation for selective catalytic reduction of NO with NH3 at low temperatures
TL;DR: In this paper, a series of manganese-cerium oxide catalysts were prepared by co-precipitation method and used for low temperature selective catalytic reduction of NO x with ammonia in the presence of excess O 2.
Journal ArticleDOI

Gongshin Qi,Ralph T. Yang +1 more
TL;DR: In this paper, a series of manganese-cerium oxide catalysts were prepared by different methods and used for low-temperature selective catalytic reduction (SCR) of NO x with ammonia in the presence of excess O 2.
Journal ArticleDOI
Strontium-doped perovskites rival platinum catalysts for treating NOx in simulated diesel exhaust.
TL;DR: It is shown that a strontium-doped perovskite catalyst, prepared from more abundant (and cheaper) elements, may help to lower the cost of NOx treatments and thus ultimately make diesel a more cost-effective automotive fuel.
Journal ArticleDOI
Low-temperature selective catalytic reduction of NO with NH3 over iron and manganese oxides supported on titania
Gongshin Qi,Ralph T. Yang +1 more
TL;DR: In this paper, a series of catalysts of manganese oxide supported on TiO 2 and iron-manganese oxide support with different amounts of Manganese and iron were studied for low-temperature selective catalytic reduction (SCR) of NO with ammonia in the presence of excess oxygen.
