First synthesis of air-stable NiZn homogeneous alloy nanoparticles through chemical reduction

We successfully synthesized NiZn homogeneous alloy nanoparticles, which were mixed at the atomic level, for the first time through a chemical reduction method with sodium-naphthalenide as a reducing agent. The NiZn alloy nanoparticles were stable even in air for at least half a year, although Zn is...

Summary:We successfully synthesized NiZn homogeneous alloy nanoparticles, which were mixed at the atomic level, for the first time through a chemical reduction method with sodium-naphthalenide as a reducing agent. The NiZn alloy nanoparticles were stable even in air for at least half a year, although Zn is typically easily oxidized. Air-stable NiZn homogeneous alloy nanoparticles were synthesized by sodium-naphthalenide-driven reduction at the controlled reduction speed of Ni and Zn ions.
