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

ABSTRACT: Nickel foam modified by hollow sphere NiCo₂O₄ particles was successfully prepared via a hydrothermal method using nanosphere SiO₂ particles as the hard template for the hollow structure. Characterisation using SEM-EDX and TEM confirmed the structure as multiwalled hollow spheres with an average size of 270 nm, while characterisation using SEM, XRD, and XPS confirmed that the NiCo₂O₄ particles were attached on the surface of the nickel foam. BET analysis showed that the surface area of the synthesized NiCo₂O₄@Ni foam was nearly three times higher compared to that of the unmodified Ni foam.
