| titleOfInvention | Graphene-metal oxide composite material and preparation method thereof |
| abstract | The invention discloses a graphene-metal oxide composite material and a preparation method thereof. The preparation method of the graphene-metal oxide composite material comprises the following steps of: (1), diluting a graphene oxide material, ultrasonically dispersing to obtain a graphene oxide solution; (2), adding cerate (or zircon salt) to the graphene oxide solution, and ultrasonically dispersing again to obtain a mixed solution; (3), adding auxiliaries in the mixed solution; (4), ultrasonically dispersing the mixed solution until the solution is clear without particles, adding hydrazine hydrate and ammonia water to adjust a pH value; (5), stirring, cooling and centrifuging to obtain solids; (6), filtering the solids washing until the solids are neutral, and drying to obtain the graphene-metal oxide composite material. The preparation method of the graphene-metal oxide composite material not only can be used for improving the electric conductivity and electrochemical performances of the metal oxide, relieving the volume expansion of the metal oxides and improving the circulating stability of the metal oxides, but also can be strong in repeatable operability, simple to operate and easy for large-scale expansion. Moreover, the graphene-metal oxide composite material has light weight, high strength, high temperature resistance and high specific surface area of the graphene, and good performances including conductivity, catalysis, luminescence and the like. |
