Global kinetic modelling of the reaction of soot with O2 and NOx on Fe2O3 catalyst

Determination of Mechanism for Soot Oxidation with NO on Potassium Supported Mg‐Al Hydrotalcite Mixed Oxides

“…This kind of active oxygen is not reusable but can be replenished in the presence of gas phase O 2 . It is reported that the reaction order of O 2 is between 0.5 and 1 [19,29]. Therefore, soot oxidation with NO is slow in the absence of gas phase O 2 at lower temperatures (see Fig.…”

Facile synthesis of three-dimensionally ordered macroporous LaFeO3-supported gold nanoparticle catalysts with high catalytic activity and stability for soot combustion

“…However, the catalytic performances of 3DOM oxides are limited by their intrinsic activity, i.e., the catalytic combustion of soot over perovskite-type oxides requires a higher temperature (ca. 350-450 • C) than that of exhaust gas from a diesel engine (150-400 • C) [5][6][7][8][9][10][11][12][13][14][15][16][17][18]. It is generally known that the addition of metal (active site) to oxides can modify the intrinsic catalytic properties of themselves due to the establishment of an interaction between metal and support, which can enhance the redox properties of the modified materials [26].…”

“…The catalytic combustion of diesel soot is a typical reaction of heterogeneous catalysis containing solid particle as reactant. Noble metals, [12] transition metal oxides, [13] alkaline metal oxides, [14,15] perovskite-like type oxides [16,17] and Ce-based oxides [18] have exhibited good catalytic performances for diesel soot combustion. Especially, perovskite-like type oxides (ABO 3 ) are one of the key components in auto-exhaust treatment catalysts due to a variable valence of B-site ions and thermal stability.…”

Synergetic effects of plasma and metal oxide catalysts on diesel soot oxidation

“…In this way, soot particles can combust at lower temperatures [6]. Noble metals [7], transition metal oxides [8], alkaline metal oxides [9], perovskite-like oxides [10] and rare earth oxides [11] are some of the catalysts which exhibited good catalytic performances. Transition metal oxides such as MnO x [11], FeO x [12], CoO x [13] and CuO x [14] have been used as the main catalysts for soot oxidation because of their redox catalytic cycles.…”
