Abstract

The structure, size and morphology of nanoparticles produced by electrical explosion of Ni wire in Pt(NH3)2(NO2) 2 solution were investigated. TEM results showed the formation of Ni and Pt nanoparticles as a result of the procedure. Ni nanoparticles were formed by the explosion of the Ni wire due to the passage of high current, evaporation, ionization, and cooling in the liquid medium. Ni nanoparticles were near spherical and showed particle sizes ranging from a few nanometers up to 50 nm. Pt nanoparticles were possible formed by the dissolution of OH- in Pt(NH3)2(NO2)2 solution during the electrical explosion of the Ni wire resulting in a plasma reaction. The formed Pt nanoparticles were ellipsoidal and showed particle sizes ranging to less than 5 nm. The lattice parameter of the Pt nanoparticles almost corresponded to the standard values reported. The obtained results indicate that Pt nanoparticles can be formed from a Pt solution without a reducing agent by electrical explosion of a metallic wire resulting in a plasma reaction.
