| 英文摘要 | zr-incorporated la(ba)zrxco1-xo3-delta perovskites were prepared by a sol-gel method and used for the catalytic decomposition of the high concentrations of n2o present in propulsion applications. the introduction of zr significantly enhanced n2o conversion, esp. with x = 0.05 and 0.2 for lazrxco1-xo3-delta and bazrxco1-xo3-delta, respectively. n-2 adsorption, x-ray diffraction, temperature-programmed reduction of h-2, temperature-programmed desorption of o-2, and oxygen pulse chemisorption techniques were used to characterize the structure and redox and oxygen adsorption property of the perovskites. the increasing of the surface area, modifying of the crystal structure, more facile reducibility of cobalt species, and higher oxygen desorption-adsorption activity due to the introduction of zr were the reasons for the activity enhancement for n2o decomposition. |
