Nickel Iron Alloy Nanoparticles (Ni:Fe, Purity: 99.9%, APS: <80 nm)

Nickel Iron Alloy Nanoparticles

Nickel Iron alloy nanoparticles are a unique class of materials composed of nickel and iron, two transition metals, that are combined at the nanoscale to form nanoparticles. These nanoparticles exhibit a variety of enhanced properties due to their small size and the synergistic effects of the nickel and iron components at the atomic level.

Nickel (Ni) and iron (Fe) both have excellent magnetic properties, and when combined, they form a range of alloy compositions that can enhance characteristics such as magnetism, electrical conductivity, corrosion resistance, and chemical stability.

Properties of Nickel-Iron Alloy Nanoparticles

Magnetic Properties: Ni-Fe nanoparticles are ferromagnetic and exhibit strong magnetic behavior, making them ideal for applications in data storage, magnetic sensors, and catalysis.

High Surface Area: Due to their nanoscale size, these nanoparticles have an increased surface area to volume ratio, which enhances their reactivity and makes them effective in catalytic processes and energy storage.

Electrical Conductivity: Nickel and iron both have good electrical conductivity, which can be enhanced in the alloyed nanoparticle form, enabling their use in electronic and magnetic applications.

Applications

Catalysis:

Hydrogenation Reactions: Ni-Fe nanoparticles are often used as catalysts in hydrogenation reactions, where they help convert unsaturated compounds into saturated ones. This application is particularly valuable in the chemical and petrochemical industries for processes such as the hydrogenation of oils and fats.

CO2 Reduction: Ni-Fe alloy nanoparticles are studied for their role in catalytic processes to reduce carbon dioxide (CO2) into valuable chemicals, helping to mitigate the effects of climate change.

Energy Storage and Batteries:

Supercapacitors: Nickel-Iron alloy nanoparticles are used in supercapacitors due to their high surface area and excellent conductivity, providing efficient charge storage and release. They are particularly effective in hybrid energy storage systems where both high energy and power densities are needed.
