Properties, Storage and Cautions:
Nickel nanoparticles possess 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 nanopowder form, they are highly reactive, flammable, and prone to oxidation, requiring strict safety measures.
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 cause oxidation, agglomeration, or hazardous reactions. To ensure stability and safety, the nanopowder should be stored sealed under vacuum or in an inert atmosphere, in a cool, dry, and dark environment, minimizing particle coagulation, moisture absorption, and thermal degradation.
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 applications due to high coercivity and magneto-crystalline anisotropy.
-
Additive Manufacturing and Composites: Serves as a sintering additive and reinforcement in metal and ceramic matrices, improving mechanical strength and electrical/thermal conductivity.
-
Propellants: Functions as a combustion catalyst in solid and liquid propellants, increasing burn rates and energy output.
-
