英文摘要in this work, a novel system of water/2-propanol/1-butanol (w/ip/nb) was developed to synthesize la1-xbaxmn2al10o19 (x = 0, 0.05) catalysts. these catalysts were also synthesized by the hydrolysis of the alkoxides in distilled water. the physicochemical properties of the catalysts were characterized by transmission electron microscopy, x-ray powder diffraction, and n-2 adsorption isotherm measurements. the effects of the reaction medium and drying method on the properties of the catalysts were investigated. the results showed that la0.95ba0.05mn2al10o19 catalyst synthesized in w/ip/nb had a higher activity in methane combustion (t-10% = 425 degrees c; t-10% = the temperature at 10% methane conversion) than that prepared in distilled water (t-10% = 515 degrees c). after the reaction was run at 700 degrees c for 100 h under the reaction conditions, la0.95ba0.05mn2al10o19 catalyst synthesized in w/ip/nb showed a higher stability than that prepared in distilled water. the lamn2al10o19 synthesized by subcritical drying showed a higher activity (t-10% = 440 degrees c) than that prepared by conventional oven drying. la0.95ba0.05mn2al10o19 catalyst showed a higher activity than lamn2al10o19, which was ascribed to the partial substitution of ba for la. furthermore, the structure property of water in w/ip/nb was investigated by means of ft-ir, nmr, electric conductivity, and laser light scattering granulometry. it was proposed that a novel reverse microemulsion of w/ip/nb is formed by distilled water, 2-propanol, and 1-butanol. the hydrolysis of the alkoxides in w/ip/nb was controlled efficiently, just as in a conventional reverse microemulsion.
