Manganese nanopowder has antifungal and antibacterial activity. Manganese nanoparticles possess unique magnetic properties and also have great potential applications in the environmental protection field as a new generation of environmentally friendly catalysts. It is used as a starting material for the manufacturing of manganous salts, used as an additive in fertilizers and as a reagent in textile printing.

This is a promising material because of its characteristic physical and chemical properties. It exhibits broad applications, for instance, ion exchange, molecular adsorption, energy storage, catalysis, biosensor. It also shows variant catalytic and adsorptive properties. These are also employed as magnetic nanoparticles for magnetic storage data and magnetic resonance imaging (MRI).

Manganese oxides have established applications in ion-exchange reactions, as cathode materials for rechargeable batteries and as distinguish agents for magnetic resonance imaging (MRI). The manganese nanopowder is utilized to enhance the mechanical and thermal properties of polymers and also to improve the ionic conductivity of polymer electrolytes. It is well known by its catalytic properties in different selective oxidation processes, for instance, H2O2 decomposition.

The size, structure, chemical composition, and morphology can be controlled for the distinctive properties and the applications. The oxide of manganese has been employed in electrode manufacturing and selective catalytic oxidation applications, for instance, nitrogen and carbon oxide elimination in the exhaust gas, as well as in the preparation of magnetic materials.
