| description | The shape and morphology of nanostructures play a crucial role in determining their electrochemical performance, offering a promising strategy for enhancing glucose sensing capabilities through structural optimization. In this study, a novel three-dimensional porous cobalt oxide (Co₃O₄) nanorod-like structure was synthesized via a facile hydrothermal method and investigated as an efficient catalyst for glucose detection. The influence of hydrothermal temperature on the morphology and electrochemical properties of the synthesized materials was systematically examined. Comprehensive characterization techniques were employed to analyze the composition and crystal structure of the samples. Electrochemical performance, particularly glucose oxidation activity, was assessed using cyclic voltammetry (CV), electrochemical impedance spectroscopy (EIS), and amperometry. The optimized 3D porous Co₃O₄ nanorod-like structures exhibited outstanding glucose sensing performance, featuring a broad linear detection range from 0 to 2.0 mM , high sensitivity of 343 µA·mM^−1 · cm^−2, and a low detection limit of 0.251 µM. These findings underscore the potential of the synthesized Co₃O₄ nanorods as highly sensitive materials for advanced electrochemical glucose detection applications. |
