Hexagonal Co3O4 anchored Reduced graphene oxide Nanocomposite for High-Performance Enzymeless Glucose Sensor and Supercapacitor Applications |
| 초록 |
Reduced graphene oxide(RGO) incorporated onto metal–organic framework(MOF)-derived Co3O4 hexagons is prepared via a hydrothermal route for for supercapacitor and glucose sensor applications.The fabricated asymmetric supercapacitor cycled reversibly and exhibits high energy and power density values of 65.8Whkg−1 and 2048 Wkg−1, respectively, over the voltage range of −0.1 V to 0.4 V.The asymmetric supercapacitor shows 80.5% capacitance retention even after 5000 cycles at a current density of 4 Ag−1,which indicates its high cycling stability in view of the fact that it is binder-free. The RGO–Co3O4 hexagon-modified electrode was optimized to realize the reliable amperometric determination of glucose concentration with a very low detection limit and excellent sensitivity value of 0.4 μM and 1.315mA mM−1 cm−2, respectively. This non-enzymatic sensors showed good storage stability, repeatability, and reproducibility for the determination of glucose in biological samples. |
