| 英文摘要 | Mn-substituted ca-la-hexaaluminate rod-like nanoparticles (ca1-xlaxmnal11o19-alpha) with high surface area ranging from 47 to 80 m(2)/g for catalytic combustion of methane have been prepared using alumina sol as the (nh4)(2)co3 coprecipitation precursor and a supercritical drying (scd) method. ca substitution gave rise to the maximum combustion activity (t-10% = 459 degrees c) at x = 0 owing to the highest surface area. meanwhile, ca substitution affects the oxygen sorption property and the oxidation state of mn ions in the hexaaluminate lattice. ca0.6la0.4mnal11o19-alpha catalyst with high catalytic activities was obtained owing to the excellent performance of activating oxygen.
