Catalytic NO decomposition on LaSrMn 1-x Ni x O 41d (0 B x B 1) is investigated. The activity of NO decomposition increases dramatically after the substitution of Ni for Mn, but decreases when Mn is completely replaced by Ni (x = 1.0). The optimum value is at x = 0.8. These indicate that the catalytic performance of the samples is contributed by the synergistic effect of Mn and Ni. O 2 -TPD and H 2 -TPR experiments are carried out to explain the change of activity. The former indicates that only when oxygen vacancy is created, could the catalyst show enhanced activity for NO decomposition; the latter suggests that the best activity is obtained from catalyst with the most matched redox potentials (in this work, the biggest DT and DE values). The close relationships between activity and DT or DE indicate that DT and DE are important parameters of catalyst for NO decomposition.

“…The HC-SCR method has been studied on precious metals such as Pt [3][4][5], metal oxides [6] and Ag [7,8]. It is also possible to reduce NOx with hydrocarbons on zeolites [9][10][11][12] and perovskites [13][14][15][16][17][18][19]. The main issue with HC-SCR is that the activity is very low.…”

“…Their applications in gas sensors (7), catalysts (8) or fuel cells (9) have been reported in extensive studies. BaCeO 3 oxide substituted by rare earth elements (Y, Yb, Gd, Nd, Sm, …) has been well identified as the best candidate for electrochemical devices because of its high proton conductivity (6,(10)(11).…”

BaCe0.8Zr0.1Y0.1O3-α protonic conductor coatings were co-sputter deposited from Ba, Zr and Ce0.9Y0.1 metallic targets in argon-oxygen reactive gas mixtures. The targeted composition of the coatings is obtain by fixing the discharge current applied on Zr and Ce0.9Y0.1 targets and adjusting the discharge current applied on Ba target. As deposited coatings are amorphous and present a good chemical stability against carbonation under air up to 573 K. The coatings crystallise after annealing treatment around 873 K for 2 hours under air in a mixture of BaCO3 and CeO2 in spite of the targeted double substituted BaCeO3 perovskite structure. Nevertheless, the crystallization in the convenient perovskite structure was obtained after annealing treatment under vacuum (5 ×10-3 Pa) at 873 K during 2 hours to prevent the carbonation of the coating. Such crystallized coatings kept mainly their initial morphological properties.
