Properties, Storage and Cautions:
Nickel nanoparticles exhibit a nanoscale structure that provides exceptionally high specific surface area, increased chemical reactivity, strong ferromagnetic behavior, and notable catalytic activity compared to bulk nickel. However, in this fine particulate form, they are highly reactive, flammable, and susceptible to oxidation, requiring strict handling and storage precautions.
Because of their combustibility and sensitivity to environmental conditions, the powder must be handled with extreme care, avoiding rapid movements, mechanical vibrations, and physical impacts. Exposure to air, sunlight, heat, and moisture can trigger oxidation, agglomeration, or hazardous reactions. For safety and long-term stability, the nanopowder should be stored sealed under vacuum or in an inert atmosphere, in a cool, dry, and dark environment. This reduces particle coagulation, moisture absorption, and thermal degradation, helping preserve material integrity.
Applications:
-
Catalysis: Used as an active catalyst in hydrogenation, reforming, and hydrogen evolution reactions (HER), and as support for fuel-cell reactions and carbon nanotube growth.
-
Energy storage: Applied as an electrode material for lithium-ion batteries and supercapacitors, and as a component in conductive inks for flexible electronics and printed photovoltaics.
-
Magnetic devices: Utilized in high-density data storage, ferrofluids, magnetic sensors, and microwave technologies due to high coercivity and magneto-crystalline anisotropy.
-
Additive manufacturing and composites: Serves as a sintering additive and reinforcement in metal and ceramic matrices to enhance mechanical strength and electrical/thermal conductivity.
-
Propellants: Functions as a combustion catalyst in solid and liquid propellant formulations, improving burn rates and energy output.
-
Biomedical and surface protection: Investigated for MRI contrast agents, drug-delivery systems, antimicrobial coatings, and corrosion-resistant surface layers.
