Abstract :
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).
