Confined nanospace pyrolysis for synthesis of N-doped few-layer graphene-supported yolk–shell carbon hollow spheres for electrochemical sensing

Abstract

N-doped few-layer graphene-supported yolk–shell carbon hollow spheres (CHSs/N-G) have been prepared by confined nanospace pyrolysis of GO–polypyrrole (GO–PPy) hybrids obtained by self-assembly of GO and PPy particles. More importantly, such CHSs/N-G exhibits electrochemical catalytic activity for oxidation of L-cysteine, leading to a high performance L-cysteine sensor with detection limit and linear range of 0.2 μM and 2 μM to 80 μM, respectively.
