    摘要:

    采用膠溶法合成了納米CeO2水溶膠,探討了合成CeO2水溶膠的最佳實驗條件,研究了pH值、反應物濃度、水浴溫度對膠溶過程的影響。TEM3分析表明:所制備的水溶膠中的CeO2納米粒子呈球形,約3nm,粒徑分布均勻,無明顯團聚現象;ED分析表明,CeO2納米粒子為多晶結構,并有少量單晶結構。

    Abstract:

    CeO 2 nanoparticles hydrosol was synthesized by colloidal chemical method. The optimum experiment conditions for the preparation of CeO 2 nanoparticles hydrosol were discussed. The effects of pH values, the reactant concentration and temperature on peptization process were studied. TEM photos showed that the CeO 2 nanoparticles were spherical in shape and the size was about 3nm. Particle size distribution was in narrow range, and no agglomerates were observed. ED images indicated that the CeO 2 nanoparticles were polycrystalline structure, and some of CeO 2 were monocrystal particles.
