Decomposition of nitrous oxide over supported rhodium catalysts and dependency on feed gas composition

Highly active and stable bimetallic Ir/Fe-USY catalysts for direct and NO-assisted N2O decomposition

“…In general, the higher the Ir loading, the higher the activity. In the case of Ir-USY-2%, 100% N 2 O conversion occurred at 375 8C, which is similar to the results of Li and Armor [12] and Oi et al [13] for noble metal catalysts.…”

“…In search for effective catalysts, many kinds of materials, such as metal oxides or composites [3], Fe-exchanged zeolites (FER, Beta, MFI) [4][5][6][7][8][9], transition metal doped mesoporous materials (MCM-41, SBA-15) [10,11], and noble metals loaded on various supports [12,13] have been examined to catalytically decompose N 2 O. Among these catalysts, noble metals supported on zeolites can efficiently decompose N 2 O at the temperatures of 250-350 8C [12].…”

Strong dispersion effect of cobalt spinel active phase spread over ceria for catalytic N2O decomposition: The role of the interface periphery

“…However, for practical applications this problem can be easily solved by dispersion of cobalt spinel active phase on a high surface area support such as alumina, silica, magnesia or ceria [29,30,31,32,33,34,35]. Among them CeO 2 , owing to its particular properties (redox and oxygen storage capacity), in many cases appeared to be superior for deN 2 O catalytic application [36].…”

The effect of C(s) on the trapping of NOx onto Pt/Ba/Al2O3 catalysts

“…Once the trap is saturated a pulse of hydrocarbons over the material reacts to release NO, regenerate the BaO sorbent material and reduce the NO to N 2 [4][5][6][7][8][9][10]. The first step in this cycle is the oxidation of NO (over Pt) to form NO 2 [11,12].…”
