The invention discloses a high - sensitivity Co3O4 porous nano - sheet non-enzymatic glucose sensor and a preparation method thereof, belonging to the field of electrochemical sensors. The Co 3 O 4 porous nanosheet prepared by the present invention shows excellent analytical performance in electrochemical detection of glucose, such as high sensitivity (8506 μA mM ‑1 cm ‑2 ), short response time (less than 6s), and low detection limit (1μM), good selectivity and stability. In particular, the sensitivity is as high as 8506 μA mM ‑1 cm ‑2 , which is the highest sensitivity compared with other Co 3 O 4 non-enzymatic glucose electrochemical sensors so far. In addition, the preparation method of the Co 3 O 4 porous nanosheets is simple and pollution-free, and the process of preparing the glucose electrochemical sensor is simple, which has a high commercial application prospect. |
