Embodiment 1

[0022] The first step, inject 10 milliliters of pure water in the beaker of 50 milliliters, dissolve 1 millimole manganese acetate in water and stir to form clear solution, then dissolve 1 millimole sodium sulfate therein and stir to obtain manganese acetate aqueous solution. In addition, 10 ml of pure water was injected into a 50 ml beaker, 4 mmol of manganese acetate was dissolved in water to obtain a clear solution, and 0.4 g of polyvinylpyrrolidone was dissolved therein and stirred to obtain an aqueous solution of polyvinylpyrrolidone.

[0023] The second step is to mix and stir the manganese acetate aqueous solution and the polyvinylpyrrolidone aqueous solution for 30 minutes, then transfer it into a stainless steel autoclave with a polytetrafluoroethylene liner with a volume of 35 ml, and add pure water to 70% to 90% of the volume of the kettle , the kettle was sealed, and put into a high-temperature oven at 180° C. to react for 24 hours.

Abstract

The invention provides a method for preparing a manganic manganous oxide nano-material, belonging to the field of nano-magnetic material technology. The method comprises the following steps of preparing a manganese acetate solution and a polyvinylpyrrolidone solution; preparing manganese-contained solid salt, and carrying out washing treatment and drying treatment. The method prepares the manganic manganous oxide nano-material by one-step synthesis, changes the sorts of simple inorganic salt modification agent and the appearance of the outcome simultaneously, is simple and convenient, has feasible operation and high yield, and is safe, environment-protective and convenient for control.

Description

technical field [0001] The invention relates to a preparation method in the technical field of nano-magnetic materials, in particular to a preparation method of trimanganese tetraoxide nano-material. Background technique [0002] mn 3 o 4 It is an important inorganic material with a wide range of uses. In the electronics industry, it is the raw material for the production of soft ferrite, which is widely used as a magnetic recording material; in the chemical industry, it can be used as a catalyst for various reactions. In addition, Mn 3 o 4 It can also be used as a colorant for some paints or coatings, containing Mn 3 o 4 Paints or coatings sprayed on steel have better corrosion resistance than paints or coatings containing titanium dioxide or iron oxide. In addition, Mn 3 o 4 It can also be used as the positive electrode active material spinel LiMn for the preparation of batteries 2 o 4 precursors, etc. mn 3 o 4 Due to the small size effect, quantum effect, su...
