Oxide Nanopowder

Manganese dioxide nanoparticles synthesized by distinct methods such as hydrothermal method, co-precipitation method, sol-gel, precursor technique, wet chemical route, etc. It is the most attractive inorganic material due to its physical and chemical properties. This compound has wide applications in catalysis, molecular adsorption, biosensor, ion exchange, biosensors, and energy storage devices. These nanoparticles are utilized in various fields for instance in coatings, textile industry, biosensors, etc. These are also employed as magnetic nanoparticles for magnetic storage data and magnetic resonance imaging (MRI).

Nanomaterials, having a length scale less than 100 nm, have received increasing interest owing not only to their fundamental scientific significance but also to the potential applications that derive from their fascinating electrical, magnetic, and catalytic properties MnO2 nanoparticles are used as a colorant and decolorizer in glass, whiteware, enamels, and pottery. It is also used in battery cathode mixes and electronics. There is promising potential to use MnO2 in solid-state lithium-ion batteries for automobiles. MnO is used in ferromagnetic ferrites and as a catalyst.

Manganese oxides, including MnO, MnO2, and Mn3O4, are intriguing composites and have been used in wastewater treatment, catalysis, sensors, supercapacitors, and alkaline and rechargeable batteries. Particularly, MnO and MnO2 nanomaterials have attracted great interest as anode materials in lithium-ion batteries (LIBs) for their high theoretical capacity, low cost, environmental benignity, and special properties.

Rechargeable magnesium battery (rMB) has received increased attention as a promising alternative to current Li-ion technology. Since the first commercialization, rechargeable Li-ion battery (LIB) has dominated the market of the secondary battery industry and now it is the primary energy source in portable electronic devices. Without any doubt, their dominance will continue and expand to other fields such as electronic vehicles and stationary stations where the large-scale output and storage of energy is essential.

MnO2 nanoparticles are also used as a pigment and as a precursor to other manganese compounds, such as KMnO. It is used as a reagent in organic synthesis, for example, for the oxidation of allylic alcohols. The predominant application of MnO2 is as a component of dry cell batteries: alkaline batteries and zinc-carbon batteries. Other industrial applications include the use of MnO2 as an inorganic pigment in ceramics and in glassmaking.
