| description | The invention discloses a three-dimensional graphite alkene/cobaltosic oxide composite material and a preparation method thereof. The three-dimensional graphite alkene/cobaltosic oxide composite material comprises graphite alkene and cobaltosic oxide and has a three-dimensional micrometer or three-dimensional nano porous structure, and the cobaltosic oxide is uniformly distributed on the surface of the graphite alkene. The preparation method comprises steps that, an oxidation graphite alkene dispersion liquid and a divalent cobalt salt dispersion liquid are firstly prepared, the oxidation graphite alkene dispersion liquid and the divalent cobalt salt dispersion liquid are then mixed, uniform ultrasonic dispersion is realized, after oil bath temperature control, centrifugation and washing for the mixed oxidation graphite alkene/ divalent cobalt salt liquid are carried out, the oxidation graphite alkene is further added, uniform ultrasonic dispersion is realized to acquire the mixed oxidation graphite alkene/ cobalt hydroxide liquid, hydro-thermal reaction generates, graphite alkene/ cobaltosic oxide hydrogel is obtained, through pre-freezing and freeze-drying treatment, the three-dimensional graphite alkene/cobaltosic oxide composite material having specific capacity up to 748F/g and having good circulation and multiplying power performance is acquired. The preparation method has advantages of simple and reliable operation, low cost and environmental-protection performance. |
