| 中文摘要 | the aim of this work is to study the effect of sr substitution on the redox properties and catalytic activity of la2-xsrxnio4 (x = 0.0-1.2) for no decomposition. results suggest that the x = 0.6 sample shows the highest activity. the characterization (tpd, tpr, etc.) of samples indicates that the x = 0.6 sample possesses suitable abilities in both oxidation and reduction, which facilitates the proceeding of oxygen desorption and no adsorption. at temperature below 700 degrees c, the oxygen desorption is difficult, and is the rate-determining step of no decomposition. with the increase of reaction temperature (t > 700 degrees c), the oxygen desorption is favorable and, the active adsorption of no on the active site (no + v-o + ni2+ -> no--ni3+) turns out to be the rate-determining step. the existence of oxygen vacancy is the prerequisite condition for no decomposition, but its quantity does not relate much to the activity. |
