摘要

本文介绍了一种简单的水热合成方法，用于在石墨烯纳米结构上可控地生长氧化钴纳米颗粒。Co3O4颗粒是单分散性的，粒径小于10 nm，均匀地锚定在石墨烯片上。考察了氧化剂、反应温度和反应时间对产物微观结构的影响。用透射电镜(TEM)和高分辨率透射电镜(HRTEM)对所得材料进行了表征。

Controllable preparation and characterization of graphene-based cobalt oxide nanocomposites

Here we introduce a facile hydrothermal synthesis for the controllable growth of cobalt oxide (Co3O4) nanoparticles onto graphene nanostructures. The Co3O4 particles were monodispersive with a grain size less than 10 nm and homogeneously anchored on graphene sheets. The effects of oxidants, reaction temperatures, and reaction times on the microstructures of final products were investigated, respectively. The obtained material was characterized by transmission electron microscopy (TEM) and high-resolution TEM (HRTEM).
