摘要
通过燃料-硝酸盐低温燃烧法合成了纳米二氧化铈粉体.考察了新型燃烧剂甘油和甘露醇对二氧化铈纳米粉体的影响,通过TG-DTA对凝胶的分解特性进行了分析,并利用XRD、氮气吸脱附和SEM对粉体的性能进行了表征.结果表明:使用甘露醇制备的CeO2晶粒较小(10.1 nm),比表面积较大(87.1 m2.g-1).
Nanosized CeO2 powder was synthesized by fuel-nitrate low-temperature combustion method. The effect of novel fuels （glycerol, and manninol） was studied. The gel decomposition was analyzed by TG-DTA, and the properties of the powders were characterized by XRD, nitrogen adsorption/desorption and SEM. The results showed that nanosized CeO2 powder prepared with manninol had smaller crystalline size （10.1 nm） and higher BET area （87.1 m^2 ·g^-1）.
