| 英文摘要 | Series of Ba1-xLaxFeAl11O19-delta hexaaluminate catalysts were prepared by (NH4) 2CO3 co-precipitation method and their performance for methane catalytic combustion was studied. The obtained materials were characterized by XRD, Diffuse UV-Vis, FT-IR, TPR, and N-2 BET techniques. The results showed that partial substitution of Ba with La in Fe-hexaaluminates could enhance catalytic activity for methane combustion, and the optimal catalyst was Ba0.2La0.8FeAl11O19-delta hexaaluminate, whose light-off temperature was as low as 495 degreesC denoted by 10% conversion of methane (V-CH4/V-O2/V-N2 = 1/4/95). XRD and SEM characterization indicated that the samples formed well-defined hexaaluminate phase after calcination at 1 200 degreesC for 5 h, and the dopant of La could promote the formation of hexaaluminate phases. UV-Vis-DR characterization revealed that the oxide state of Fe is + 3 in Ba1-xLaxFeAl11O9-delta catalysts. The synergism between Ba, La and Fe was observed based on the results of UV-Vis-DR, FT-IR and TPR. |
