摘要:

以Ce(NO3)3*6H2O与(NH4 )2 CO3*H2O为原料,并加入少量的PEG600作为分散剂,应用快速化学沉淀法合成Ce2 (CO3)3*8H2O前驱体,前驱体经过热处理以后,获得了纳米CeO2,对样品进行XRD、DTA、TEM、BET和光谱分析与表征,根据慢扫描,通过高斯算法计算CeO2晶粒大小.结果表明:前驱体经过300℃焙烧后完全变成了CeO2,颗粒粒径为10～20 nm 左右,晶粒尺寸为5.7 nm,比表面积为111.68 m2/g,纯度>99.97%.

Abstract:

Taking Ce(NO3)3*6H2O and (NH4)2 CO3*H2O as raw materials, and adding a small amount of PEG600 as a dispersant, Ce2 (CO3)3*8H2O precursor was synthesized by rapid chemical precipitation, and after heat treatment, nano-CeO2 was obtained, XRD, DTA, TEM, BET and spectral analysis and characterization were carried out on the sample, and the CeO2 grain size was calculated by Gaussian algorithm according to slow scanning. The results showed that the precursor completely turned into CeO300 after roasting at 2°C, the particle size was about 10~20 nm, the grain size was 5.7 nm, the specific surface area was 111.68 m2/g, and the purity was >99.97%.
