| 英文摘要 | the inverse ceo2/la2sn1.7co0.3o7-delta was prepared by sol-gel and impregnation method calcined at 900 degrees c and investigated in the methane catalytic combustion. the catalytic activity evaluated for methane combustion showed that the methane conversion temperature of t-90 was 564 degrees c, compared with the pure la2sn1.7co0.3o7-delta prepared in the same condition and mechanical mixing of la2sn1.7co0.3o7-delta and ceo2, t-90 decreased by 78 degrees c and 135 degrees cc, respectively, and the inverse la2sn1.7co0.3o7-delta catalyst not only had the excellent methane combustion activity, but also had the well thermal stability and reusable performance. the excellent performance of the inverse la2sn1.7co0.3o7-delta catalyst was represented by the characterizations of xrd, tem, afm, tpr, bet, xps and mossbauer spectra. xrd characterization showed that the inverse la2sn1.7co0.3o7-delta catalyst not only had the la2sn1.7co0.3o7-delta structure, but also had the ceo2 phase, and the ceo2 had been well disperse on the la2sn1.7co0.3o7-delta composite oxide; tpr indicated that the la2sn1.7co0.3o7-delta had lower reduction temperature compared to la2sn1.7co0.3o7-delta xps and mossbauer spectra indicated that the sn4+ is the main valence state in the inverse catalyst, and the lattice oxygen play an important role in catalytic activity; tem and bet tests showed that the la2sn1.7co0.3o7-delta particles had better dispersed and larger surface area than la2sn1.7co0.3o7-delta. all above explained the reasons of the la2sn1.7co0.3o7-delta catalyst had excellent catalytic activity toward methane combustion. |
