| 英文摘要 | With the introduction of mg2+ into fe-substituted la-hexaaluminate precursors, a series of monophasic lamgxfeal11-xo19 (x = 0, 0.3, 0.7, 1) catalysts were prepared and tested as catalysts for ch4 catalytic combustion. the results show that the introduction of an appropriate amount of mg2+ (x = 0.7) could significantly enhance the catalytic activity of fe-substituted la-hexaaluminates and promote the resistance to deactivation after calcination at 1300 degrees c. the beneficial effect of mg2+ is attributed to the fact that the presence of mg2+ not only increased the distribution of fe3+ in the mirror planes of la-hexaaluminates but also effectively suppressed the generation of catalytically inactive fe2+. besides, the lamg0.7feal10.3o19 catalyst exhibits excellent stability for 100 h at 700 degrees c under the reaction conditions. |
