▎ 摘　　要

Co(2)Nx/nitrogen-doped reduced graphene oxide (Co(2)Nx/NG) is synthesized by electrostatic co-precipitation of Co and rGO followed by high-temperature nitridation, which can serve as an efficient catalyst for sensitive glucose detection due to the unique electrocatalytic property of Co(2)Nx and synergistic effect between Co(2)Nx and N-doped rGO.
