The present invention relates to the fast preparation methods of a kind of graphene-based metal of sandwich structure or metal oxide.The preparation method of the graphene-based metal of the sandwich structure or metal oxide includes the following steps：Graphene oxide and metal amino complex solution are prepared respectively；Metal amino complex solution is added drop-wise in graphene solution, generates precipitation；Precipitation is collected, is heated at high temperature under inert gas shielding；Obtain the graphene-based metal or metal oxide with sandwich structure.Graphene-based metal or metal oxide compounds prepared by this method has the advantage that：Preparation method is simple and quick, can largely prepare graphene-based metal or metal oxide compounds, and compound has sandwich structure, and metal or metal oxide particle have nano-scale, and metal or metal oxide particle are highly dispersed between graphene layer.Therefore, which has excellent chemical property, can be used as the electrode material of lithium battery and ultracapacitor. |
