MnO2 manganese dioxide nanoparticles as an important transition metal oxide has been widely used in many fields such as battery materials. It is a very stable black powder solid at room temperature, can be used as a dry battery depolarizing agent.

MnO2 preparation raw materials easy to obtain, good repeatability, and no pollution, conducive to industrial production;

MnO2 has a large specific surface area, which can increase the contact between the active substance and the electrode, reduce the internal resistance of the battery, improve the ion diffusion performance, and has a high electrochemical capacity and good high power and high rate discharge performance.

Manganese dioxide MnO2 nanoparticles has a good application prospect in the fields of electronics, catalysis, electronic sieve, ceramics, especially as electrode materials for supercapacitors, and has a broad application market.

1. Electrode material:

MnO2 is a very important raw material in the battery industry. It has the characteristics of large discharge capacity, strong activity, small size, long life and no pollution to the environment. Nanometer manganese dioxide MnO2 is used as battery cathode material. It has been widely used in Zn/MnO2 dry batteries, Mg/MnO2 batteries, Zn/MnO2 batteries, and can be used in non-aqueous solvent electrolytes, such as Li/MnO2, lithium secondary batteries.

Manganese dioxide has good Faraday capacitance and can be used as electrode material for electrochemical supercapacitors instead of expensive ruthenium oxide.

2. Electrochromic application:

The materials used for electrochromism are required to have good ionic and electronic conductivity, high contrast, color changing efficiency and cycle time. Inorganic electrochromic materials, mainly transition metal compounds or hydrates. Inorganic electrochromic materials can be divided into cathodic coloring materials in the reduction process according to the coloring method. For example, WO3 changes from colorless to blue in the reduction process. And oxidation process anode coloring materials, such as MnO2, change from light yellow to dark brown during oxidation. At present, WO3 has been extensively studied and applied in electrochromic Windows, and MnO2 is considered to be one of the anode chromic materials with the most potential development.

3. Catalytic application

Nano manganese dioxide has been widely used in catalysis because of its special nanometer size effect and good REDOX properties. In organic synthesis, alcohols can be oxidized to ketones by using MnO2 as catalyst. MnO2 has a high removal rate of phenol. In the inorganic catalytic decomposition, MnO2 has a good effect on the decomposition of sodium hypochlorite and hydrogen peroxide.

4. Biosensor application

In recent years, the application of manganese dioxide in biosensors has been developed because of its good catalytic properties to hydrogen peroxide. At the same time, it is friendly to the environment. Biosensors using manganese dioxide for glucose detection have been extensively studied.

5. More Applications. Nano manganese dioxide, for example, is also a very good decolorizing agent in glass manufacturing, which can oxidize cheap iron salts into high iron salts, making the blue green in glass into weak yellow. Steel industry used as iron manganese alloy raw material, casting industry heating agent. Desiccant for paint and ink, etc.

Manganese dioxide is packed in inert plastic bags, sealed and stored in dry and cool environment, should not be exposed to air, prevent moisture oxidation agglomeration, affect the dispersion performance and use effect.
