Pure Nickel (Ni) and Nickel–Palladium (Ni–Pd) alloy were electrodeposited on graphite surface via pulse electrolysis in dimethyl sulfoxide in form of rods and nanoparticles with a diameter of ∼100–350 and ∼10–35 nm, respectively. X‐ray photoelectron spectroscopy (XPS) spectra of Ni 2p 3/2 region for these nanomaterials suggests on their surface Ni 2+ precursor while after Ar + ion‐etching metallic nickel starts to be dominated. Both Pd 0 and Pd 2+ for XPS spectra of Pd 3d 5/2 and 3d 3/2 were observed after electrodeposition. Scanning electron microscope‐energy dispersive X‐ray and XPS analysis confirmed electrodeposition of nickel nanomaterials in non‐aqueous electrolyte. Using a lower concentration of Ni 2+ precursor, nanoparticles with an average particle size of ∼10–23 nm were prepared on a graphite surface.
