“…Copper based catalysts for direct decomposition of N 2 O-N 2 have been reported [27,28]. Most of the catalysts are supported ones where Cu is supported on metal oxides and perovskits [29][30][31][32][33][34][35]. Zeolite supported Cu catalysts are also studied for N 2 O decomposition [36,37].…”

A series of Cs promoted copper oxide catalysts were prepared by co-precipitation method and tested for the direct decomposition of nitrous oxide (N 2 O). The Cs promoted catalysts were more active particularly with a molar ratio of Cs/Cu at 0.1 compared to bulk CuO. Methods of XRD, BET, XPS, H 2 -TPR, and N 2 O-TPD were used to characterize these catalysts to evaluate structure activity relationship. The characterization results indicated that the addition of Cs could improve the reduction of Cu 2? -Cu 0 by facilitating the desorption of adsorbed oxygen species, during the N 2 O decomposition. The influences of oxygen and steam on N 2 O decomposition over these catalysts were also studied.

“…nitrogen and oxygen. Wide variety of catalysts were tested such as metal surfaces [8], supported metals [9][10][11], metal oxides [12,13], supported oxides [14,15], ternary oxides [16], spinels [13,[17][18][19][20][21][22][23][24][25], perovskites [26] hydrotalcites [27][28][29], and zeolites [30][31][32][33][34][35][36][37]. Focusing our attention to spinel oxide catalysts, a high laugh gas decomposition activity was reported for cobalt containing spinel oxides, such as Co 3 O 4 .…”

In this paper, nitrous oxide decomposition over a series of MCO 3 -Co 3 O 4 (M = Ca, Sr, Ba) catalysts having M/Co ratios of 0.1-0.4 has been studied. The various catalysts were characterized using thermal (TGA, DTA), XRD, IR and N 2 sorption techniques. N 2 O decomposition activity was found to be dependent on the type of the alkaline earth cation, the M/Co ratio, cobalt oxide crystallites sizes, and the calcination temperature.

“…Many catalytic materials are reported to be able to catalyze the N 2 O decomposition; among them are supported metals or noble metals (in particular, Rh, Pd, and Pt on alumina, zirconia, and titania) [5][6][7][8][9][10], metal-ion exchanged zeolites (in particular, Cu, Fe, Co in ZSM-5, BEA, and Beta structures) [11][12][13][14][15][16][17][18], and mixed oxides (in particular, perovskites, hydrotalcites) [19][20][21][22][23][24][25][26][27][28][29][30]. Only very few of them have been developed commercially (e.g., the Uhde EnviNOx Ò process [31]), showing enough activity or stability to be useful under practical conditions.…”

Direct catalytic decomposition of N 2 O in inert and oxidative atmosphere was investigated over two series of binary oxide catalysts containing CuO coupled with Ga 2 O 3 or SnO 2 dispersed over a silica-alumina support (CuGa/SA and CuSn/ SA series catalysts). The activity for N 2 O decomposition in the absence of oxygen was between 0.1 and 0.2 lmol g cat s -1 in the 500-600°C interval over the CuSn/ SA series catalysts with conversion between 80 and 90%. Lower activities with larger differences were observed within the CuGa/SA series catalysts. The presence of oxygen in the feed (O 2 /N 2 O ratio up to 20:1) did not affect the activity of the CuGa/SA series while a light decrease of activity could be noticed on the CuSn/SA series. The effect of methane reductant in the selective N 2 O reduction (N 2 O-SCR) was tested. On the CuGa/SA series samples, the best reaction selectivity was observed.
