Porous, thick nitrogen-doped carbon encapsulated large PtNi core-shell nanoparticles for oxygen reduction reaction with extreme stability and activity
Abstract
We encapsulate large Pt shell/Ni core (PtNi) particles with thick and porous nitrogen-doped carbon (N–C) layers, and demonstrate that the thick N–C layers can protect the PtNi particles from dissolution and migration for an extremely long service life through both steric hindrance and chemical bond; in addition, the well mass transfer performance of the porous N–C, the thin Pt shell, and the promotion effects of N–C and Ni on Pt lead to...
