| 英文摘要 | la0.5sr0.5mno3 single-crystal cubes and nanoparticles were synthesized by hydrothermal and citrate routes, respectively. their catalytic properties for low-temperature co oxidation and high-temperature ch4 combustion were evaluated, and the effects of crystal structure and morphology on the catalytic properties of the catalysts were investigated. the activity (220 degrees c of the complete oxidation of co over the single cubes was lower than that (190 degrees c over the nanoparticles. after running at 600 degrees c for 48 h under the reaction conditions, the surface area of the nanoparticles decreased significantly, but the cubes nearly maintained their surface area. for ch4 combustion, the la0.5sr0.5mno3 cubes showed a higher activity (t-10 = 360 degrees c, t-10: the temperature at 10% conversion of ch4) than the nanoparticles (t-10 = 440 degrees c. the different activities were attributed to their different crystal structures and morphologies.
