Abstract

The invention discloses a method for preparing a ferroferric oxide / carbon / nano-graphite sheet nanocomposite material in situ and relates to preparation of inorganic nanocomposite materials. The problems that the physical properties are reduced or the ferroferric oxide is non-uniform in load in the process of preparing the ferroferric oxide / graphene composite material or in the graphene oxidation-reduction process are solved. The method comprises the following steps: adding a ferric iron salt, a ferrous iron salt, expanded graphite and a carbon-based compound into water containing a reaction promoter for mixing, performing ball milling by using a ball mill, thereby obtaining a composite dispersion system with good dispersion; mixing the composite dispersion system and a substance which can be heated to decompose a hydroxide ion, adding the mixture into a closed high-pressure hydrothermal reaction kettle, reacting at high temperature, taking out the reaction product, performing suction filtration, drying, grinding, thereby obtaining the ferroferric oxide / carbon / nano-graphite sheet nanocomposite material. The method disclosed by the invention is used for preparing the ferroferric oxide / carbon / nano-graphite sheet nanocomposite material in situ.

Description

technical field

[0001] The invention relates to the preparation of inorganic nanocomposite materials. Background technique

[0002] Fe 3 o 4 Nanoparticles possess superparamagnetism and magnetic tunneling effect, coupled with their advantages of non-toxicity and biocompatibility, so they have a wide range of applications as a functional material. Due to its superparamagnetism, when the nano-ferric oxide solution is placed in an external magnetic field, the sample will be attracted to the side of the magnetic field; when the magnetic field is removed, the ferric oxide particles will re-disperse in the water. Utilizing the magnetic responsiveness of ferroferric oxide, a series of functional composite materials with magnetic field responsive characteristics can be prepared, which can be widely used in the fields of targeting carrier, material separation, environmental water treatment and so on. Fe 3 o 4 It also has the advantages of high theoretical specific capacity, abun...
