Theoretical study on NOx adsorption properties over the α-MnO2(110) surface

“…The sorbents CuO, SnO 2 , CeO 2 , Al 2 O 3 , TiO 2 , and V 2 O 5 have been chosen as the ideal materials to remove NO x in industries. [12][13][14][15] However, the high cost of these noble metal oxides limits their application; therefore, there is a need to nd inexpensive materials to remove NO x efficiently. Chen et al found that a-MnO 2 exhibits the highest adsorption capacity for NO x among the a-, b-, gand s-MnO 2 phase structures and the abovementioned sorbents.…”

Pushing the Limits of Precious Metal Atom Economy for Three-Way-Catalysts (TWC): Thermally Stable and Highly Active Single Rh Atom Catalysts (Rh1/ceria) Under Both Dry and Industrially Relevant Conditions for NO Abatement

“…Various technological advances have allowed to decrease the NO emissions from vehicles significantly relying on so-called "three-way-catalysts (TWC)" and, more recently, selectively catalytic reduction technology (SCR). [1,[3][4][5][6][7][9][10][11]32] TWC is widely used in a multitude of trucks, regular cars, motorcycles, lawnmowers and such. [1,[3][4][5][6][7] Various industrial formulations exist with Pd and Rh being the main components supported on materials with oxygen storage capacity, such as ceria, ceria-zirconia and others.…”

Identification of Ru/Ceria Among Single Atom Ceria Catalysts as a Stable and Superior Material for Abatement of Diesel and Gasoline Engine Pollutants

“…Air pollution is one of the main issues to tackle in environmental science and catalysis [1][2][3]. Deteriorating air quality is directly related to toxic NOx emissions, the majority of which are produced by vehicles exhaust.…”
