摘要：
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 mu M and 2 mu M to 80 mu M, respectively.
