报道以流变相 前驱物法制备纳米Co3O4的一种新的软化学方法。先用流变相法合成草酸盐前驱物CoC2O4·2H2O,再在不同温度下热分解可制备得纳米CO3O4。通过热重法(TG)、X 射线衍射(XRD)和透射电子显微镜分析了其前驱物、产物的颗粒大小及形状等特征。研究了分解温度与产物粒径大小之间的关系以及微晶生长动力学。从实验结果可以看出,流变相 前驱物法为制备纳米Co3O4粉末提供了一种简单、可行、有效的方法。 Reported a rheological phase precursor preparation of nano-Co3O4 a new soft chemical method. First, rheological phase synthesis of oxalate precursor CoC2O4 · 2H2O, and then at different temperatures can be prepared by thermal decomposition of nano-CO3O4. The precursors, particle size and shape of the product were characterized by TG, XRD and TEM. The relationship between the decomposition temperature and the particle size of the product and the growth kinetics of the microcrystals were investigated. It can be seen from the experimental results that the rheological phase precursor method provides a simple, feasible and effective method for preparing nano-Co3O4 powder.
