| 英文摘要 | catalytic activity of pt catalysts for soot oxidation was studied using temperature programmed reactions. the activity of pt loaded over tio2-sio2 (pt/tio2-sio2) showed higher activity than other pt/mox systems (mox = tio2, zro2, sio2, al2o3. tio2-zro2. tio2-al2o3, zro2-sio2, zro2-al2o3, sio2-al2o3). the activity was highest when the molar ratio of tio2/(tio2 + sio2) ranged from 0.4 to 0.7. the effect of pretreatment with a gas containing low so2 concentrations on the activity was compared for pt/sio2, pt/tio2 and pt/tio2-sio2. in the case of pt/tio2-sio2, the activity was markedly promoted by the pretreatment whereas no variation in the activity was observed for pt/sio2. the difference in the behavior towards the so, pretreatment was attributed to property difference in the supports for sulfate accumulation. the high activity of pt/tio2-sio2 was also confirmed under practical conditions with a diesel engine exhaust using a catalyst-supported diesel particulate filter (dpf).
