Current densities of five Au@Ni/C electrodes in 0.1 M NaOH containing 5 mM glucose at 0.10 V by amperometric measurements (The current densities were normalized to the first electrode) (A); current densities of 5 mM glucose in 0.1 M NaOH solution tested every half day by amperometric measurements (The current densities were normalized to the first day) (B), the current densities are the average values of triplicate determinations; CVs of the Au@Ni/C (C) and Au/C (D) electrode with the presence and absence of different concentration of Cl− ions.
