Abstract

NiCo₂O₄ nanosheets with sheaf-like nanostructure morphologies have been synthesized by a facile one-step hydrothermal reaction followed by annealing treatment. Impressively, the NiCo₂O₄ nanosheets exhibit rapid detection of eugenol. The linear range of detection is from 1–500 μM, and the limit of detection is 5.4 pM. The NiCo₂O₄ modified electrode demonstrated high sensitivity, good repeatability and reproducibility, and long-term stability (7% decrease in response over 30 days). Based on this work, an electrochemical reaction mechanism for eugenol oxidation was proposed, and in addition, the NiCo₂O₄ modified electrode was successfully employed for the analysis of eugenol in medicative balm samples. Recovery values for eugenol in medicative balm samples were in the range 98.7%–105.5%. [Figure not available: see fulltext.]
