Ni Coated Multi-walled Carbon Nanotubes (MWCNTs) are widely used in various advanced applications due to their unique properties. They are particularly valued in the field of electronics, where they serve as conductive fillers in nanocomposites, enhancing electrical conductivity and mechanical strength. These nanotubes are also employed in energy storage devices, such as lithium-ion batteries and supercapacitors, where they improve electrode performance by increasing surface area and facilitating electron transfer.

In catalysis, Ni Coated MWCNTs are utilized as efficient catalysts or catalyst supports in chemical reactions, including hydrogenation and fuel cell applications, due to their high surface area and stability. Additionally, they are used in sensors for detecting gases and biomolecules, offering high sensitivity and selectivity. Their magnetic properties, imparted by the nickel coating, make them suitable for applications in magnetic data storage and biomedical fields, such as targeted drug delivery and magnetic resonance imaging (MRI). Overall, Ni Coated MWCNTs are versatile materials with significant contributions to nanotechnology and advanced material science.
