Manganese Dioxide (MnO2) Nanoparticles (MnO2, 98%, 50nm)

Manganese Dioxide (MnO2) Nanoparticles  Main purpose: good bleaching agent in the battery industry and glass industry; organic synthesis catalyst; paint and ink drying agent; ferrite magnetic materials; important doped materials for voltage sensitivity and temperature-sensitive resistors.

Energy Storage and Conversion

Lithium-Ion Batteries (LIBs): Manganese dioxide nanoparticles are widely used in the development of lithium-ion batteries as a cathode material. The nanoparticles enhance the performance of the cathode by increasing the surface area and allowing for better charge/discharge cycles, improving the overall capacity and stability of the battery. Manganese dioxide-based cathodes are considered more affordable and environmentally friendly compared to traditional cobalt-based alternatives.

Supercapacitors: MnO₂ nanoparticles are utilized in supercapacitors due to their high electrochemical activity and large surface area. They can store and deliver energy rapidly, making them ideal for applications that require quick bursts of power, such as in electric vehicles, portable devices, and regenerative braking systems.

2. Catalysis

Environmental Catalysis: Manganese dioxide nanoparticles are widely used in environmental applications, particularly in air and water purification. They act as effective catalysts in oxidation reactions, helping to degrade harmful pollutants like volatile organic compounds (VOCs), nitrogen oxides (NOx), and sulfur compounds. MnO₂ nanoparticles can also be used in water treatment to remove heavy metals, such as arsenic, lead, and mercury, through adsorption and redox reactions.

Organic Synthesis: MnO₂ nanoparticles are employed in organic reactions as selective oxidants. They can selectively oxidize alcohols to aldehydes or ketones without affecting other functional groups in a molecule, which is crucial for fine chemical production in pharmaceuticals and agrochemicals.

Carbon Dioxide Reduction: MnO₂ nanoparticles can catalyze the reduction of CO₂ to useful chemicals or fuels, which is an important process in carbon capture technologies. This makes MnO₂ nanoparticles a promising material for carbon capture and utilization (CCU), helping to mitigate the effects of climate change.

Environmental Remediation

Heavy Metal Removal: MnO₂ nanoparticles are highly effective in removing toxic heavy metals (such as lead, arsenic, and mercury) from contaminated water. They work through a combination of adsorption and oxidation processes, rendering heavy metals less toxic and easier to remove from water systems.
