| titleOfInvention | Cobalt oxide nanocrystal-graphene composite material, its preparation method and use |
| abstract | The embodiment of the present invention provides a cobaltous oxide nanocrystalline-graphene composite material. The embodiment of the present invention also provides a preparation method of a composite material, comprising: 1), adding graphite oxide to a first organic solvent and dispersing; 2), adding cobalt acetylacetonate and octadecylamine, and heating the mixture to 120 ℃ ～140℃, maintained for 20～50 minutes, then warmed up to the boiling reflux of the solution, maintained for 1～5 hours; 3), adding the second organic solvent to quench the reaction, separating the solid, washing and drying the solid; 4), drying the The resulting solid is heat treated in an inert gas for 1 to 3 hours. The embodiment of the present invention also provides an application of the composite material as a positive electrode catalyst in an organic system Li-O 2 battery. In the composite material provided by the embodiment of the present invention, cobalt oxide nanocrystals are uniformly grown on the graphene substrate, with good dispersibility and no agglomeration, so that the composite material has better catalytic performance. |
