摘要：

In this work, we have triumphantly synthesized porous NiCo2O4 nanowires array on nickel foam (NiCo2O4 NWs/NF) via a facile hydrothermal method. Benefiting from its great one-dimensional porous nanowires architecture along with synergistic interactions between NiCo2O4 arrays and Ni foam, the NiCo2O4 NWs/NF-based sensor exhibited enhanced glucose sensing performance. The sensitivity could reach up to 5916 mu A mM(-1) cm(-2), meanwhile, the linear range was 1 mu M-3.987 mM with a low detection limit (LOD) of 0.94 mu M (S/N = 3). Furthermore, it displayed good selectivity. These results inspire that the porous NiCo2O4 nanowires will be a promising candidate for non-enzymatic glucose sensors. (C) 2019 Elsevier B.V.
