Nano-iron has a wide range of downstream applications and good industry development prospects

Nano-iron is iron particles formed by superposition of iron atoms at the nanometer level, including spherical nano-iron and flake nano-iron. Compared with ordinary iron, the physical properties of nano-iron are basically the same, and the toughness has been improved to a certain extent. However, the chemical properties have changed. Nano-iron has improved corrosion resistance and can spontaneously ignite or even explode in the air.

Nano-iron can be prepared by physical methods and chemical methods. The physical preparation methods of nano-iron mainly include evaporation and condensation, high-energy ball milling, deep plastic deformation, etc. Among them, the high-energy ball milling preparation process has weak control capabilities in terms of product purity and particle uniformity. The chemical preparation methods of nano-iron mainly include solid/liquid/vapor phase chemical reduction method, microemulsion method, electrodeposition method, pyrolysis method, high temperature hydrolysis method, active hydrogen-molten metal reaction method, etc. There are many methods for preparing nano-iron, which can be flexibly selected according to investment scale, technical strength, and market demand.

According to the “2021-2025 Nano-Iron Industry In-depth Market Research and Investment Strategy Suggestions Report” released by the Industrial Research Center, nano-iron The particle size is small, the specific surface area is large, and it has excellent tunnel effect and boundary effect. It has the physical properties of ordinary iron, and its chemical properties change, and it can be used in a wide range of downstream applications. Nanoiron can be used to produce absorbing materials, electromagnetic shielding materials, invisible materials, magnetic permeable slurries, magnetic recording materials, magnetic fluids and other materials. It is widely used in data storage, electronics, lighting, precision equipment, mechanical equipment, medical equipment, sealing Shock absorption, magnetic printing, military industry and national defense and other fields.

Nano-iron can also be used as a catalyst and reducing agent. For example, in the production of organic silicon, catalysts can promote and accelerate reactions. Traditional organic silicon catalysts use platinum, which has scarce resources and high prices. However, organic silicon has a wide range of downstream applications and large annual output, so new cost-effective catalysts can replace it. The demand is urgent. Nano-iron has good catalytic properties and can be used in the preparation process of silicone. In addition, nano-iron can also be used in catalytic water splitting, organic matter degradation and other fields.

my country has a large population and is also a major manufacturing country. It emits a large amount of organic waste every year. Nano-iron can be used in the field of organic wastewater treatment. In the “Nano Frontier” key project of the “14th Five-Year Plan” national key R&D plan, it is proposed to construct a nano-iron-microbial collaborative technology process system; to carry out the practical application of nano-iron-microbial collaborative treatment of organic wastewater with low biodegradability and low carbon to nitrogen ratio. verify. This will accelerate the development of nano-iron in the field of organic wastewater treatment and increase the demand for nano-iron.

Industry analysts said that nano-iron has more properties of ordinary iron. After being made into nano-materials, its chemical properties change. , and obtains new functions such as tunnel effect and boundary effect, so the application fields are different from traditional iron. Nano-iron preparation processes are diverse and can be used in a wide range of downstream applications. Policies are still promoting its development in the field of environmental protection. Overall, my country’s nano-iron industry has good development prospects in the future.
