Abstract

We present the use of silica-polydopamine (SiO₂@PDA) core-shell nanoparticles (NPs) as self-confined templates for the fabrication of ultra-stable hollow Pt anchored N-doped carbon nanospheres (Pt/HN-C). SiO₂@PDA nanospheres were fabricated by a facile one-pot process, followed by the deposition of Pt NPs onto the outer shell layer. The confinement and adhesion of the PDA framework ensured the distribution and stability of Pt NPs after carbonization at the carbon shell layer. The converted Pt/HN-C exhibited excellent catalytic performance and durability for the oxygen reduction reaction (ORR).
