| 英文摘要 | hydrothermal synthesis by using urea. hydrolysis at 1.0-3.0 mpa and 120-130 degreesc was employed to prepare mn-substituted hexaaluminate catalysts for methane combustion. the results from dta-ms demonstrated that co32- and oh- anions co-exist in the hydrothermal reaction. xrd reveals that the components of carbonates and hydroxides in the hydrothermal reaction are more favorable than those in the (nh4)(2)co3 co-precipitation for the formation of the mn-substituted hexaaluminate phase. after calcination at 1,200degreesc for 2 h, lamnal11o9 is the major phase of the catalyst prepared by the hydrothermal synthesis method while laalo3 is the major one of the catalysts prepared by nh4oh and (nh4)(2)co3 co-precipitation. the catalyst prepared by hydrothermal synthesis has higher activity than that prepared by nh4oh and (nh4)(2)co3 co-precipitation. the major reason is that more mn2+ ions have incorporated into the hexaaluminate lattice. the effect of drying methods on the formation of hexaaluminate phase was also discussed. |
