Sulfur-Mediated Synthesis of Spherical Nickel Nanoparticles in a Chemical Vapor Reactor

[Image: see text] In this study, we investigated the effect of the sulfur content in the NiCl(2) precursor on the shape of nickel nanoparticles (Ni-NPs) prepared by chemical vapor synthesis. We obtained spherical Ni-NPs when using anhydrous NiCl(2) mixed with NiSO(4) or Na(2)SO(4) with a molar ratio...

Sumario:[Image: see text] In this study, we investigated the effect of the sulfur content in the NiCl(2) precursor on the shape of nickel nanoparticles (Ni-NPs) prepared by chemical vapor synthesis. We obtained spherical Ni-NPs when using anhydrous NiCl(2) mixed with NiSO(4) or Na(2)SO(4) with a molar ratio of 0.002 as precursors without changing any other process parameters whereas faceted Ni-NPs when using only anhydrous NiCl(2) as a precursor. First-principles calculations supported experimental results, which showed that NiSO(4)-mixed NiCl(2) and Na(2)SO(4)-mixed NiCl(2) precursors favored the growth of spherical NPs.
