英文摘要: Abstract(#br)The catalytic decomposition of nitrous oxide to nitrogen and oxygen has been investigated over various solid oxide solutions (SOS), La 0.8 Sr 0.2 MO 3−δ (M=Cr, Fe, Mn, Co or Y), La 1.8 Sr 0.2 CuO 4−δ and supported Pd, Pt catalysts. The reaction was carried out in a gradientless recycle reactor at 1 atm pressure with a feed gas containing about 0.5% N 2 O (in helium). Among the various solid solutions, La 0.8 Sr 0.2 CoO 3−δ showed a maximum N 2 O conversion of 90% at 600‡C. The order of activity observed for N 2 O decomposition was La 0.8 Sr 0.2 CoO 3−δ >La 0.8 Sr 0.2 FeO 3−δ >La 1.8 Sr 0.2 CuO 4−δ > La 0.8 Sr 0.2 MnO 3−δ La 0.8 Sr 0.2 CrO 3−δ ≈La 0.8 Sr 0.2 YO 3−δ . The activity of La 0.8 Sr 0.2 CoO 3−δ was compared with supported Pd, Pt and also with unsubstituted LaCoO 3...
