绒球状氧化钴微晶的控制合成及表征

Controlled Synthesis and Characterization of Fluff Sphere-like CoO Microcrystals

用一种简单的方法制备了绒球状氧化钴微晶。通过调控高分子化合物PVP的用量控制反应前驱体的形貌从而控制了最终产物氧化钴的形貌。通过比较PVP的用量对产物形貌的影响分析了相应的反应机理。用X射线粉末衍射(XRD)和扫描电镜(SEM)对CoO微晶的晶相和形貌进行了表征。

The paper thinks that it is feasible for the fluff sphere - like CoO microcrystals to get it prepared through a facile method. By adjusting the amount of polymer PVP, the morphology of the final product CoO can be determined by the morphology of the precursor. The corresponding mechanisms have been analyzed by comparing the effect of PVP on the morphology of the products. The phase and morphology of the CoO microcrystals have been characterized by XRD and SEM.
