以乙二胺四乙酸(EDTA)、Co(NO3)2·6H2O、冰醋酸、钛酸丁酯为原料,采用溶胶-凝胶燃烧法制备得到了CoTiO3纳米粉体.先将反应物制成凝胶前驱体,然后在干燥条件下以10 ℃/min的速率升温,用TG-DAT进行表征,结果测得其热分解和晶化温度在450 ℃以上.将此前驱体在700 ℃下焙烧2 h,制备得到了CoTiO3纳米粉体.对此纳米粉体以X射线衍射(XRD)、热重分析(TG)、透射电子显微镜(TEM)、傅立叶转换红外光谱仪(FT-IR)、紫外-可见分光光度计(UV-vis)进行表征,结果表明所制备的纳米CoTiO3粉体由粒径为30~90 nm的多边形颗粒构成,平均粒径约为70 nm.
