Preparation of nickel foam modified by multiwalled hollow spheres of NiCo2O4 as a promising non-enzymatic glucose sensor

Nickel foam modified by hollow sphere NiCo 2 O 4 particles was successfully prepared via a hydrothermal method. Investigation of the NiCo 2 O 4 -modified nickel foam as an electrode for the detection of glucose in sodium hydroxide solution showed high linearity of the anodic currents.
