| Zusammenfassung: | The nanometer complex oxide La0:7Sr0.3Mn0.6Zn0.₄O₃ was prepared by using a Sol-Gel method
with citric acid as a ligand. The in
uence of Zn doping of La0.7Sr0.₃MnO₃ on the structure,
the morphology, the surface properties and on the catalytic activity of material was studied by
using X-ray diraction (XRD), transmission electron microscopy (TEM), a high-resolution images
and selected area electron diraction (SAED), physical adsorption and temperature programmed
surface reaction (TPSR) methods. The results showed that perovskite La0:7Sr0:3Mn0:6. Zn0.₄O₃
could well catalyse propene oxidation in the temperature range 190 { 280 ℃, which was reduced
to 100 { 120 ℃ for catalyst La1-χSrχMnO₃ KCI Citation Count: 1 |
