Preparation method of graphene inorganic nanocomposite

Abstract

The invention discloses a preparation method of a graphene inorganic nanocomposite, which comprises the following steps: firstly, adding grapheme into the aqueous solution of soluble inorganic salt, and scattering the grapheme by ultrasound; then adding precipitant under the mixing condition, centrifuging at a high speed and heat treating the obtained mixed liquor, and finally obtaining the graphene inorganic nanocomposite. The composite has high surface area, adjustable diameter of nano particles, and important application value on catalysis, stored energy, drug delivery and the like.

Description

technical field

[0001] The invention relates to a method for preparing a graphene inorganic nanocomposite material by using graphene as a raw material in a one-step direct method, belonging to the technical fields of nanomaterials and functional material chemistry. Background technique

[0002] Graphene is a single-layer carbon atomic surface material exfoliated from graphite material, which is a two-dimensional structure of carbon. This thin film of graphite crystals is only 0.335 nanometers thick. Graphene, like graphite, belongs to the compound hexagonal lattice, and each carbon atom in the two-dimensional plane is sp 2 The hybrid orbitals are connected, that is, three σ bonds are formed between each carbon atom and the three nearest neighbors. The remaining p-electron orbit is perpendicular to the graphene plane, forming π bonds with surrounding atoms, and the carbon atoms surround each other to form a regular hexagonal planar honeycomb structure. Graphene has excelle...
