| Summary: | 碩士 === 逢甲大學 === 化學工程學所 === 95 === In this study, mesoporous CeO2 and mesoporous CuO/CeO2 are synthesized by traditional precipitation method. The experimental parameters, such as precursors, precipitants, reaction time and temperature, and calcination temperature were investigated . The resulting materials were characterzed by TGA, BET, X-ray, VVSEM, FESEM, and TEM spectroscopy.
The results show that, all samples are mesoporous structure and cubic fluorite structure. With the experimental parameters of reaction temperature at 90 ℃, reaction time at 30 hours, temperature at 90 ℃, NaOH as precipitant and Ce(NO3)3．6H2O as the precursor, the specific surface area of sample is 171.4 m2/g. With different Cu and Ce ratio synthesize mesoporous CuO/CeO2, the specific surface area of CuO/CeO2 is 171.9 m2/g for the sample of CuO/CeO2 molar ratio equals 1:19.
