Nickel Carbon Core Shell Nanoparticles (Ni/C, 99.9%, APS: 80-100nm, Metal Core/Carbon Shell)

Nickel Carbon Core-Shell Nanoparticles

Applications

Energy Storage and Conversion:

Supercapacitors:

Nickel Carbon Core-shell nanoparticles have been explored for use in supercapacitors due to their high surface area, electrical conductivity, and magnetic properties. The carbon shell enhances the energy storage capacity, while the Nickel core contributes to charge/discharge efficiency and electrical conductivity.

Batteries:

The high conductivity of the Ni core combined with the graphitic structure of the carbon shell makes these nanoparticles ideal for use in Li-ion or Na-ion batteries. They can serve as efficient electrode materials, improving the capacity and cycle stability of the battery.

Fuel Cells:

The catalytic properties of Nickel make Ni/C nanoparticles useful in fuel cell technology, particularly for hydrogenation reactions or oxygen reduction reactions (ORR). The carbon shell helps in preventing oxidation of the Nickel core, thus improving the stability and lifetime of the catalyst in fuel cells.

Catalysis:

Hydrogenation Reactions:

The Nickel core is a well-known catalyst for hydrogenation reactions, such as the hydrogenation of unsaturated hydrocarbons. The carbon shell protects the Nickel core from oxidation and enhances the nanoparticle’s stability and efficiency during the reaction.

Electrocatalysis:

Ni/C nanoparticles can serve as electrocatalysts in fuel cells, water splitting, or CO₂ reduction reactions. The carbon shell can stabilize the catalyst, improving its efficiency and durability in electrochemical processes.

Pollutant Degradation:

The catalytic activity of Ni/C nanoparticles also extends to environmental applications, such as the degradation of organic pollutants in water or air. The carbon shell offers a surface for adsorption, and the Nickel core catalyzes the breakdown of the pollutants.

Biomedical Applications:

Magnetic Targeting and Drug Delivery:

The magnetic properties of the Ni core enable magnetic targeting of therapeutic agents, which can be used to direct the nanoparticles to specific tissues or organs (e.g., tumors). The carbon shell can be functionalized with drugs or biomolecules, enabling controlled release for targeted drug delivery.

Magnetic Resonance Imaging (MRI):

Due to their magnetic properties, Ni/C core-shell nanoparticles can be used as MRI contrast agents. The ability to control the size and magnetic properties of these nanoparticles allows them to provide enhanced imaging and tissue contrast, which can improve the detection and diagnosis of diseases.
