    • Abstract

       

      Pt nanoparticles were deposited on NiCo alloy nanosheet arrays using carbon papers as substrates to fabricate the disposable non-enzymatic glucose sensing electrodes. The electrochemical performance of NiCo-Pt nanosheet arrays were systematically investigated. The NiCo-Pt-3 electrode displayed the best glucose sensing performance with high sensitivities of 4903.43 and 2258.21 ${\mu}$A·mM$^{–1}$·cm$^{–2}$ in the wide linear ranges of 1 ${\sim}$M–8 mM ($R^2$ = 0.999) and 8 mM–20mM ($R^2$ = 0.996), respectively. The detection limit at 0.6 V was about 0.25 ${\sim}$M (S/N = 3). The incorporation of Pt greatly improved the electrocatalytic activity of NiCo-Pt-3 for glucose oxidation, during which Pt can not only act as the chargetransfer promoter to improve the catalytic activity of NiCo alloy, but also serve as electrocatalyst for direct glucose oxidation. Moreover, NiCo-Pt-3 also demonstrated high selectivity and preferable feasibility for serum sample analysis.The study of the NiCo-Pt-3 nanosheet array may provide a promising way to construct highly efficient non-enzymatic glucose sensors.
