A new insight into electrochemical detection of eugenol by hierarchical sheaf-like mesoporous NiCo2O4
In this work, NiCo2O4 nanosheet with sheaf-like nanostructure morphologies was synthesized by a facile one-step hydrothermal reaction followed by annealing treatment. Impressively, the NiCo2O4 exhibit rapid detection of eugenol. The linear range of detection is from 1-500 µM, and the limit of detect...

| Summary: | In this work, NiCo2O4 nanosheet with sheaf-like nanostructure morphologies was synthesized by a facile one-step hydrothermal reaction followed by annealing treatment. Impressively, the NiCo2O4 exhibit rapid detection of eugenol. The linear range of detection is from 1-500 µM, and the limit of detection is 5.4 pM. 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. The recoveries study for eugenol in medicative balm samples gave values in the range of 98.7– 05.5%. |
