Synthesis method for platinum-nickel alloy materials with core-shell dispersion structure on a carbon support (Pt–Ni / C) and the materials obtained from this method.

Abstract

The invention relates to a method for synthesizing Pt-Ni / C core-shell structured materials, including the steps of adding Pt precursor salts and Ni precursor salts to a solution containing PVP with EG, stirring to obtain a homogeneous solution, then adding carbon to anchor the PtNi material on this carbon substrate, filtering, washing and drying, and finally calcining the material system at 300-350°C to obtain the Pt-Ni / C core-shell structured material. The invention also proposes the material obtained from this process.
