Embodiment 1

[0045] 1.9291 g Fe(OOC(CHOH) 4 CH 2 OH) 2 ·2H 2 O (with Fe 2+ Expressed as 0.0833 mol / L) added to 48.00 mL H 2 After stirring and dissolving in O, transfer to a polytetrafluoroethylene reactor and react at 200 ℃ for 10 h. After the reaction, the solid product was washed with absolute ethanol and secondary water, then placed in an oven and dried at 90-100 ℃ for 9-11h to obtain composite FF / LGO-1.

[0046] A certain amount of this material was soaked in a 6 mol / L HCl solution for 24 hours, and the Fe in the composite material was calculated according to the mass change before and after soaking. 3 O 4 The actual compounding amount is 41.2%. The magnetization of the composite material is 68.8 emu / g.

Embodiment 2

[0048] Fe(OOC(CHOH) 4 CH 2 OH) 2 ·2H 2 The added amount of O is 2.8933 g (with Fe 2+ The molar concentration of is expressed as 0.1250 mol / L), and other conditions are the same as in Example 1, the obtained composite material FF / LGO-2. Fe in the composite 3 O 4 The actual compounding amount is 41.0%; its magnetization is 58.2 emu / g.

Embodiment 3

[0050] Fe(OOC(CHOH) 4 CH 2 OH) 2 ·2H 2 The added amount of O is 3.8575 g (with Fe 2+ The molar concentration of is expressed as 0.1667 mol / L), and other conditions are the same as in Example 1, the obtained composite material FF / LGO-3.

[0051] Fe in the composite 3 O 4 The actual compounding amount is 40.6%; its magnetization is 50.3 emu / g.

Abstract

The invention provides a method for preparing a ferroferric oxide / graphene oxide-like magnetic nanocomposite by taking ferrous gluconate as a single raw material. The single Fe<2+> ferrous gluconate is taken as the iron source and the carbon source; H<2>O is taken as the solvent; the Fe<3>O<4> with high magnetic property and magnetic nanocomposite Fe<3>O<4> / LGO with the graphene oxide-like structure carbon (LGO) are prepared by one step through a hydrothermal method by controlling the hydrothermal conditions. According to the method, any other additive (such as an alkali precipitator, an oxidizing agent, a catalyst, a surfactant and the like) is not required; surface modification of the Fe<3>O<4> material is not required either; the generation and effective compounding of the Fe<3>O<4> and the LGO are realized in one step; the Fe<3>O<4> / LGO magnetic composite material with strong interphase interaction is prepared; and in addition, the magnetic nanocomposite has the outstanding advantages of simple process, short process, low cost, green and environment-friendly performance and the like, so that the industrialization of the magnetic nanocomposite can be promoted.

Description

Technical field [0001] The present invention relates to a ferroferric oxide / graphene oxide-like (Fe 3 O 4 / LGO) Preparation of magnetic nanocomposite materials, especially related to a ferrous gluconate Fe(OOC(CHOH) 4 CH 2 OH) 2 One-step preparation of Fe for a single raw material 3 O 4 The / LGO magnetic nanocomposite material method belongs to the field of nanomaterial technology. Background technique [0002] The rapid development of chemical science has brought huge material achievements to mankind, but also caused negative effects such as environmental pollution, ecological crisis and energy waste. Therefore, people advocate the concept of green chemistry: safe and non-toxic, simple to synthesize, The product has excellent performance, etc., to minimize the negative effects on the environment and humans from the source. [0003] In recent years, Fe 3 O 4 / C magnetic composite materials have a wide range of applications in adsorption materials, electromagnetic shielding, microwa...
